advent of code solutions

Unfortunately, I am just an amateur. The code checking if a pixel is drawn bright or dark: Now we just need to apply it to all pixels one by one and render the final result: Notice that when doing list comprehensions in Erlang the order of generators matters. Now lets take a look at how scoring can be conveniently calculated: Again a keen observer might notice that it could be done in a single function, but I think most people will agree that translating the specifications one-to-one is way more convenient and much easier to understand and possibly debug if the need arises. I assumed that the list of elves is not empty, so I start with its first element as the current max and then started comparisons with other elves. Such comparisons can be done by a surprisingly simple function: We already know which files are to be counted when a directory size is calculated. The fun is that these puzzles can be solved in any programming language and are accessible for Notice that for each of the operations, I use the fold (lists:foldl/3 to be more specific) function instead of the map function. Advent of Code is an advent calendar of challenging but accessible coding challenges with a new puzzle released each day during December. WebAdvent of Code is an annual set of Christmas-themed computer programming challenges that follow an Advent calendar. This requires an insignificant code change, to build, store and process 2 paths instead of one. For those who do not know, Advent of Code is a fun and inclusive event which provides a new programming puzzle every day. If you are interested in looking more into how I did that, take a look at the code here. For each shape, there is a comment above on how the shape is drowned. For part 2, the most obvious solution has complexity $O(n^3)$ where The Elves take turns writing down the number of Calories contained in the various snacks that theyve brought with them, one item per line. Lets start by looking at the input data. Annual Revenue Estimate $500,000 to $1 million; SIC Code show 7372, Prepackaged Software; Employees 5 to 9; Contacts show; Owner Steve Sandy; Reviews (0) Write a Review. (https://en.wikipedia.org/wiki/Cellular_automaton). Keep track WebFor more information about Rydberg Technologies, products and services, research and development thrusts, collaborations and partnerships, or any other inquiries please contact us via email at [emailprotected], by phone at (734) 330-2836, or using the contact form below. Then I run a query to create STEP relations between nodes. However, since the set of possible heights is small (there are only 10), we can For part 1, just simulate the rounds. Then we need to check if any of the lists of visibility (up, down, left and right) have all of the elements smaller than the considered tree. We need to check if sand starts falling below the lowest rock. Now there is just a minor rearrangement of the checking views function: So notice I know two of the `VisibilitySides` are being reversed to process them from the viewers perspective. In this puzzle, we need to divide each input line in half and then find the intersection (a single element) of the first and second half of each line. Having this predicate defined, we just need to run it for all of the trees in the grid and count how many of them are visible from the outside. The first puzzle is about finding the best production plan (how many geodes they can produce at most in 24 steps for 30 blueprints. I prepared a visual to help understand how to determine those squares: In the example above, there are three pairs of sensor + beacons. The first task is to find how many assignment pairs in one range, fully contains the other. Before traversing the tree, change the value of To get the final score (which is a sum of the games scores) we then sum all of the elements of the list. To get initial values, I ran the example simulation and tuned the values until they returned a correct answer. Complete Python solutions for Advent of Code 2022. For reproducibility, I also provide a development container to reproduce the exact same environment in a Docker container under Visual Studio Code with Microsoft Remote Development . Use a doubly-linked list. For part 2, consider a graph where Now the partially parsed crates look like this: Next for a list of parsed rows, I picked the heads of those lists to a separate list (my first stack) and then reapplied the same function recursively for the tails of those rows (to deliver the following stacks). To be more precise, both of todays puzzles are almost identical. It turned out that instead of: In the event that I was unable to locate my mistake, I would recommend implementing unit tests, hoping not to duplicate the mistake there. Lets propose the representation of the board as a list of ranges (each range representing a row or its part. Finding the answer to the first puzzle is just parsing pairs of packets. Find your place in tech on #TeamAmex. WebAdvent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. This represents how many squares are left to be used going each way along the row starting from X being the sensors X. The second approach is leveraging the erlang sets module: Playing around with multiple implementations and checking if they all work correctly I added some unit tests at the end of the module. (If a tree is right on the edge, at least one of its viewing distances will be zero.). Find your place in tech on #TeamAmex. Lets take a look at some ideas for optimisation to make the waiting time bearable. When the robot is set, it produces one resource each turn. the floor). by some factor. take a list of valves, and the initial paths (that is a single path containing exactly one valve [AA] (our starting point)). Find the elf with the highest calories and save this elf as the first one. Fortunately, the amount of memory taken is the size of the / directory. A tag already exists with the provided branch name. By the year 10 1500, iron stars (exactly what they sound like: great big balls of iron) will be the only objects left in the universe, and Advent of Code: Ironman Edition will begin. https://github.com/aleklisi/AdventOfCode2022/tree/main/day20_puzzle1. Today, both puzzles are about finding directories and the sizes of files and subdirectories they contain. There is no point in building and checking a full matrix, as only one square is reviewed or updated at a time. An important note is that this definition works not only for two sets but for any number of sets. VOXXHirschmann Corp. is a subsidiary of VOXX International that combines domestic and international OE design, engineering, manufacturing and sales assets of Hirschmann Car Communication, Audiovox, Code Systems and Invision. This simplifies the calculation of scores and strategies. WebAdvent of Code y. So Ive provided the image above. From a mathematical/algorithmic perspective, it is all about numerical ranges (discrete intervals, aka with integers only) and finding common elements between them. For part 2, the worry levels become very large and consume a lot of memory. Last Name. Python solutions for Advent of Code 2022 Day 1. it's impossible for any rocks to land below some vertical level. Represent the nested lists as trees, and use a recursive function to compare them according to the rules. This worldwide collaboration brings together over 230 engineers and dozens of OE Automotive We need to figure out what to play, based on what our opponents move is and the expected result. updating the display in part 2) should happen before X is incremented. This is where we can implement rocks falling by simulating what they do step by step. To find all such squares for any given sensor beacon pair, we need to determine the height (Y) difference between the sensor and the row we are interested in,then cut out the respective section of the row each way. At each step, calculate the new possible combinations After sorting it remains to get only the top element for each stack. This means that worry values for each of the items will raise significantly in each next step of the simulation (especially for the monkeys that multiply the items worry level). WebOur sponsors help make Advent of Code possible: Accenture Federal Services - Technology & ingenuity moving missions forward come solve problems with us. The second part is about checking only the first 3 blueprints but with a search depth of 32. We've been making ACA compliance easy since day As always if you want to discuss, or compare your solutions with us you are welcome to do so on Twitter. But then I came to the conclusion that it would be cheating, so I also gave up this idea quickly. https://github.com/aleklisi/AdventOfCode2022/tree/main/day17_puzzle1. To make it run faster I filtered out all of the branches where the robot cannot be built: The second optimisation was to produce robots only if the supply of the resources is no bigger than the maximal potential demand per round. new floor. https://github.com/aleklisi/AdventOfCode2022/tree/main/day11_puzzle2. This can be achieved by a custom recursive function: The next step is to find the intersection of those 3 collections (which is the Elves group badge, a single character) and reuse the item for the priority conversion function from puzzle 1. 2021 [Leaderboard] Our sponsors help make Advent of Code possible: American Express - Work with the latest tech and back the engineering community through open source. Todays puzzle is all about finding a path length in a given grid. This worldwide collaboration brings together over 230 engineers and dozens of OE Automotive In the first puzzle, we need to count the number of faces of cubes that are visible. For part 2, the union of all these ranges. To get how much memory is already available,we subtract taken memory from the total space available. Secondly, pattern matching is a great tool to have, it allows us to easily implement readable code. As input, we get a list of the processors orders. Notice that instead of checking if the `contains/` predicate we could alternatively reverse the roles and check if any of the ends of the first range is in the second range. Lets now see how to achieve that in practice. But this simulation will slow down significantly after about 400 steps and reaching the 500th step took my machine over 2 minutes. Get the last 4 characters, convert to a set, and check Convert the array to integer values to make comparing elevations easier. Why does this observation matter? The distance The second puzzle adds another element, which is a horizontal sprite. We can notice that there are some valves that release 0 pressure, so it does not matter if we visit them or not with regards to how much pressure we finally release. That error was to confuse my move with my opponents move. Since running the simulation for the first few hundred (~300) steps was instantaneous, I decided not to run the normalisation of items every single step. https://github.com/aleklisi/AdventOfCode2022/tree/main/day19_puzzle1. In the first puzzle, the length is 2 and in the second puzzle, it is 10. Todays second puzzle seems to actually be simpler than the first one. Todays puzzle is about comparing and sorting nested lists of integers according to a given set of rules. If nothing happens, download GitHub Desktop and try again. In the first simulation, each time number is inspected it is divided by 5 and rounded (with the floor), while it is not the case in the second puzzle. Complete code available here: https://github.com/aleklisi/AdventOfCode2022/tree/main/day4_puzzle2. For a given $y$, a point It is needed to know how much memory is taken. The numbers are moved around based on the condition that they are dividable by a predefined number. each empty point (i.e. between them is $d = \textup{abs}(s_0 - b_0) + \textup{abs}(s_1 - b1)$. last one having equal or greater height. Notice that the same solution works for both puzzle 1 and puzzle 2. I know it sounds complicated, but lets see the code and everything should be clear. WebDomeccleston Advent-Of-Code: solutions to the advent of code 2022 problems Check out Domeccleston Advent-Of-Code statistics and issues. To find the first such sequence, I recursively check if the current 4 characters are all different. defined as the type of rock falling, the index of the jet pattern, and the location of the currently fallen rocks on SoI had to change my approach. Advent of Code is an annual, pre-Christmas series of programming tasks packaged as an Advent calendar. https://github.com/aleklisi/AdventOfCode2022/tree/main/day15_puzzle1. so after moving len(arr) - 1 positions we have passed all other members of the array are back in the original position). The second thing I would attempt to improve the simulation would be to use a set for tracking already checked cubes of steam. Full problem description: https://adventofcode.com/2022/day/1. The idea of recursion with an accumulator is basically to add another parameter to the recursive function and to store partial results in this parameter. Since the decision of handing over the item is based on the fact that this items worry level is dividable by a constant number, we can actually only care about the rest of the divisions as modifications applied by each monkey is either addition or multiplication, but since different monkeys use different dividers, you have to care about at least smallest common divider. valve AA and all non-zero flow valves). This is how the board is repeated after the area subtraction: Respectively in the third case, we eliminate some elements from the rows end for each of the given rows. For a few of the challenges, a one-liner solution was also included in the corresponding oneliners.py files. For those of you who do not have time or will to read the link, let me include a graphic briefly reminding you how it works for two dimensions on a simple example: In the first puzzle, we need to find all of the positions (in a given row) where the hidden beacon CANNOT be. WebFor more information about Rydberg Technologies, products and services, research and development thrusts, collaborations and partnerships, or any other inquiries please contact us via email at [emailprotected], by phone at (734) 330-2836, or using the contact form below. Show me the code. So here you are: In the main/1 function. You can look at the grid as if it was a graph, which gives me a perfect excuse to finally use a library that I created to communicate with the neo4j graph database and that is https://github.com/aleklisi/eneo4j/. You then filter out the ones that are not in order and then just sum the indexes of the pairs that are left. If they are then I return the result position, otherwise I remove the first character from the analysed sequence, increment the position counter by one and run the search again and so on until eventually the searched section is found. either 0, 1, or 2 (representing Rock, Paper, Scissors), and label players' choices as ind1 and ind2, then player 2 wins Based on input move the head. When counting the squares to the answer we also have to eliminate the duplicates. Since the games are unrelated (the result of previous games does not impact the next games, the best way to approach the problem is to start by implementing a single games score count function and then map a list of games with this function, to get the scores for each of the games. WebOur sponsors help make Advent of Code possible: Accenture Federal Services - Technology & ingenuity moving missions forward come solve problems with us. Day 2 of Advent of Code sees us helping the Elves to score a game of Rock, Paper, Scissors. Day 2. https://github.com/aleklisi/AdventOfCode2022/tree/main/day10_puzzle2. Now that we have an IDE set up to process our input from Advent of Code, let's check out the solutions for Day 1 2022! Take a second to notice that the first range contains the second one when both of the following conditions are met: Also spot that the second range might be the one containing the first one, so we have to reverse the condition (that is the part after `orelse`). For part 1, use dictionaries to look up the score. The data structure I decided to use to represent a single game is a two element tuple, where the first element is the opponents move and the second element is my move. remove the items as a block. Todays puzzle is finding distances between points using the Manhattan metric. to process one step at a time. When developing such code and trying to run it with an example input ,one can add `io:format`,`logger:info` or any other way of printing the intermediate steps. The fintech industry is a major disruptor. Here is the code finding all overlapping positions: Here I remove duplicates and squares that already have a beacon in it: The puzzle is not the fastest one, but it finds results within 20 seconds or so. After the DB is up and running (I used docker compose), I need to start my Erlang application and set up eneo4j app. Todays task is to implement a rope (snake-like) following its end (head). In the `read_and_parse_data/1` function I modified the anonymous function inside a map function to translate the predicted result into my move: And this is the implementation of the translating functions: Again they heavily rely on pattern matching. For part 2, build an array of all elves' calorie totals, then sort it and sum the last 3 values. The complete code is available here: https://github.com/aleklisi/AdventOfCode2022/tree/main/day8_puzzle2. So based on the observation from the previous paragraphs, we can run a normalisation for each of the items. For part 2, this approach no longer works, so we need Firstly the classical implementation: And lets compare it to the one using an accumulator: I cannot disagree that at first glance the implementation with an accumulator is more complex, but much faster code. Todays puzzle is about implementing an interpreter for manipulating crates between stacks. Since 2015, tens of thousands of programmers have tackled the new puzzles that appear every day from December 1 through 25 at the stroke of midnight (U.S. Eastern standard time). It needs to remove empty ranges and do some checking not to get incorrect ranges like this one (the left X must be smaller or equal to the right one): be simplified, but I think it is good enough as it just works. Calculate signal strength for each of those cycles and sum the calculated strengths to get the answer. This is done on purpose, so that I can easily track which requirement is met by which function closure. The fun is that these puzzles can be solved in any programming language and are accessible for Unfortunately using mapping does not work, because we need to process more than one element at a time. We will also need to define our own take_while function (similar to lists:takewhile/2) , which includes the first tree that did not meet the requirement of tree size being strictly smaller than the considered tree. The puzzle probably can be solved with some clever algorithm implementation. Day 2. This is how the code doing that looks: When there are many cases to be considered I think that the saying a picture is worth a thousand words applies. There are no reviews WebDomeccleston Advent-Of-Code: solutions to the advent of code 2022 problems Check out Domeccleston Advent-Of-Code statistics and issues. If you run out of indexes put the element back at the beginning (or end) of a list. Advent of Code 2021 Solutions in Python. Complete code available here: https://github.com/aleklisi/AdventOfCode2022/tree/main/day5_puzzle1. Notice that you can execute this function anywhere in your supervision tree and the DB will be started automatically for you when you run `rebar3 shell`. Advent of Code 2021 Solutions in Python. Firstly, notice that 3 times 5 is 15. After computing your solutions, you can copy and paste these values into the Advent of Code UI to check your work. The first one was to use the Erlang digraph module: https://www.erlang.org/doc/man/digraph.html. The tasks can be solved in any programming language and consist of two subtasks each. In practical terms. minutes (where lcm is the lowest common multiple). I found that I was not able to traverse the tree conveniently, therefore I gave it up. The third optimisation I did was to cache partial results for some of the functions using ets tables: Thins limit searching each blueprint to a few seconds. We can do this efficiently by ordering the ranges by their left edge. After creating the initial stacks of crates and a list of commands parsed, we can execute the operations. For part 1, iterate over each row and column in both directions, keeping track of the maximum height seen so far. For such data, the most convenient is a map with the following structure: In the first puzzle, we assume that the only border is created by the rocks. Advent of Code puzzles are designed to be approachable by anyone with an interest in problem-solving. For the input, we are given a list of paired ranges. I tried 2 approaches, which failed. Therefore, I will not discuss them separately. Then the code formatting reflects the same shape so that it is much easier to check each of the coordinates. For solving this puzzle it is very helpful to define a map (a data structure) of a monkey like this one: Storing a predicate in the `test` and `operation` fields for each monkey allows for certain convenience of later usage. It is an obvious mistake when you spot it, but easy oversight when reading the puzzles description fast. WebFor more information about Rydberg Technologies, products and services, research and development thrusts, collaborations and partnerships, or any other inquiries please contact us via email at [emailprotected], by phone at (734) 330-2836, or using the contact form below. The complete code is available here: https://github.com/aleklisi/AdventOfCode2022/tree/main/day8_puzzle1. The considered item (with worry level 16) will be handed in the terms (the results of the test for either of those monkeys will be the same) as the item with worry level 1. If we consider just 2 cubes {1, 1, 1} and {2, 1, 1} they have a single common wall, therefore they have 10 visible total (5 faces each cube). The second puzzle is again about running simulation, but this time the stop condition is different and there is an infinite line of rocks at MaxY + 2 line. Parse the directory structure into a graph. If the previous paragraph is confusing to you, let me give a simple example: Example: Lets consider 2 monkeys, first one is passing the item depending on the condition of the worry level is dividable by 3 and the second one is if the worry level is dividable by 5. We can introduce some optimisation and check if the sands X is smaller than the smallest X, or bigger than the biggest X. Instead, Advent of Code is a great arena for learning new skills and testing out new features of Python. Instead, Advent of Code is a great arena for learning new skills and testing out new features of Python. the smallest number in the second range is bigger or equal to the smallest number in the first range, the biggest number in the second range is smaller or equal to the biggest number in the first range. Represent coordinates as complex numbers. You dont need a heavy computer science background to participate. The programming puzzles cover a variety of skill sets and skill levels and can be solved using any programming language.Participants also compete based on speed on both global and private we need to solve an equation where humn represents the unknown value. Nor do you need a fancy computer; every problem has a solution that completes in at most 15 seconds on ten-year-old hardware. Eventually, they'll go away too, but not before 10 100000000000000000000000000 , and probably much later. Behind its doors, daily challenges are hidden, each more difficult than the previous.
