Given a rectangular matrix containing only digits, calculate the number of different 2 2 squares in it. over 1.5 years), and Python 3 has been supported since 3 Dec 2008 (i.e. Unfortunately, you don't have your watch on you and don't know what time it is. "you are? In my coding interview for a company, I got the question to write a Minesweeper game. This can be done by: In the code, we choose a random number from all possible cells in the grid. Is a collection of years plural or singular? It results in more readable code and a more logical flow than checking the bounds every time. Return an answer as the sum of digits that the digital timer in the format hh:mm would show. Each day a plant is growing by upSpeed meters. If there are several possible answers, output the smallest one. After taking care of these issues, the cell is flagged for a mine. Jun 09, 2022. minesweeper codesignal The idea to have one board with an integer to represent states is a nice idea. One of them is the IPv4 address. Assuming that your hunch is correct, decode the message. One of the most important parts of any game is sustaining the input method. You might also get some constant-factor time wins by iterating over the lists with enumerate instead of doing the for index in range() thing, and minimizing the number of extra variables you allocate. input = ["OOOXXXOXX", "XXXXXXOXX", "XOOXXXXXX", "OOXXOXOXX", "XXXXXXXXX"]. no, since [-1] is a valid index (counting from the right) ;-). Call two people equally strong if their strongest arms are equally strong (the strongest arm can be both the right and the left), and so are their weakest arms. each minute after 10th costs min11 cents. My code is GPL licensed, can I issue a license to have my code be distributed in a specific MIT licensed project? Each night that plant's height decreases by downSpeed meters due to the lack of sun heat. A string of lowercase letters. Let's define digit degree of some positive integer as the number of times we need to replace this number with the sum of its digits until we get to a one digit number. A non-negative integer representing the heaviest weight your friend can lift with his or her left arm. Is it a bug? There was a problem preparing your codespace, please try again. If the IDE doesn't highlight these, possibly change your IDE. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? When you finally decide to head back, you realize there's a chance the bridges on your route home are up, leaving you stranded! Check out the example below to see how it can move: A string is said to be beautiful if b occurs in it no more times than a; c occurs in it no more times than b; etc. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. All the effort is to be done in setting up the Minesweeper layout. A string consisting of lowercase English letters. Are you sure you want to create this branch? I presume it is trying to count bombs. A set of constraints on these variables that must be satisfied. On the upside, it's fairly space efficient, but unless you're planning on allowing giant boards, that shouldn't make much of a difference. of the docstring. Does Python have a string 'contains' substring method? Factories, factory methods and/or private methods could play a role here. The user has to clear the grid without setting off any mine. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, Python: slicing a multi-dimensional array. These methods should definitely be private. This is because the code begins running as soon as Python loads it, when the intent of the documentor was just to analyse the code. If your code is so complex that you need to explain it in a comment, you should rather try to refactor your code to be less complex so that it needs no explanation. Your task is to reverse the strings contained in each pair of matching parentheses, starting from the innermost pair. How to show that an expression of a finite type must be one of the finitely many possible values? So we have w h k x m variables here. It's still O(n) time with respect to array, though; it's not really possible to improve on that. [input] integer k This allows you to make various MineBoard methods less complex, for example: In all other places, you use row and column indexing, but in this method you're using an index. minesweeper (matrix) = [ [1, 2, 1], [1, 1, 1]] Check out the image below for better understanding: Input/Output [time limit] 4000ms (py) [input] array.array.boolean matrix A non-empty rectangular matrix consisting of boolean values - true if the corresponding cell contains a mine, false otherwise. The difference between the phonemes /p/ and /b/ in Japanese, Styling contours by colour and by line thickness in QGIS. An n-interesting polygon is obtained by taking the n - 1-interesting polygon and appending 1-interesting polygons to its rim, side by side. A string consisting of lowercase latin letters a-z. import random. Do new devs get fired if they can't solve a certain bug? First you create a list of indices, set the mines and then.. setAdjacentMines - why? For matrix = [[true, false, false], [false, true, false], [false, false, false]] the output should be . In the popular Minesweeper game you have a board with some mines and those cells that don't contain a mine have a number in it that indicates the total number of mines in the neighboring cells.. It only takes a minute to sign up. | by Leonard Yeo | The Startup | Medium 500 Apologies, but something went wrong on our end. Minesweeper is a puzzle video game. Single mine flagging due to lower-case f: I was surprised when I flagged a tile and the game ended with a mine going off. For each cell in the grid, we have to check all adjacent neighbours whether there is a mine present or not. CodeSignal Solutions with time and space complexity for the Arcade, Interview Practice, and Company Challenges. How to follow the signal when reading the schematic? This algorithm should check if the given grid of numbers represents a correct solution to Sudoku. The danger is when the code changes (due to bugs or requirement changes) from what the comment says, another coder who sees the code, and sees the comment, says "The code doesn't do that, I'll be helpful and make it do that" (I've seen this happen). The first person goes into team 1, the second goes into team 2, the third goes into team 1 again, the fourth into team 2, and so on. [input] string inputString probe would maybe be a better name. to use Codespaces. Game). Some whitespace would help draw attention to those steps: Actually, it would make even more sense to extract the various separate steps into separate functions. Check if the given string is a correct variable name. You could avoid some math to find the last item by using append, and give no argument to pop. One which just creates the string representation of the board, and a second one which prints it. For this particular concept of the game, a new data structure is used, namely, vis. All pixels at the edges are cropped. Then a nested loop on each position can go through the offsets to add 1 to the 'zero' cells when the neighbouring position is in range of the board and contains an "X": If you want to avoid messing with indexes and offsets, you can prepare 8 shifted copies of the board (one per direction) and use zip() to combine them into a tuple of neighbours for each position. The main problem is your shyness: you're afraid that you'll end up blocking the view (even if only for a couple of seconds) of all the people who sit behind you and in your column or the columns to your left. minesweeper arrayReplace evenDigitsOnly variableName alphabeticShift chessBoardCellColor circleOfNumbers depositProfit absoluteValuesSumMinimization stringsRearrangement extractEachKth firstDigit differentSymbolsNaive arrayMaxConsecutiveSum growingPlant knapsackLight longestDigitsPrefix digitDegree bishopAndPawn isBeautifulString findEmailDomain Could you please help me to check if my code follows good practices for a game-program ? First, the string is divided into the least possible number of disjoint substrings consisting of identical characters, for example, "aabbbc" is divided into ["aa", "bbb", "c"], Next, each substring with length greater than one is replaced with a concatenation of its length and the repeating character, for example, substring "bbb" is replaced by "3b". That is why any room that is free or is located anywhere below a free room in the same column is not considered suitable for the bots. I don't like that, but it's not so bad in python which is kind of designed for it. The first 8 characters of the code are 01001000, which is 72 in the binary numeral system. A good example is a set of code checking every minute "is it now 7am?" I just reversed your logic: I walk through the output field and add values from matrix. This is important because when you put out code for others to use, if they begin accessing/modifying internal class variables and you release a new version with modified internals, it will break their implementation. Given values experience, threshold and reward, check if you reach the next level after killing the monster. Some rooms are free (their cost is 0), but that's probably because they are haunted, so all the bots are afraid of them. Always use words that explain to readers what the code does through proper variable names. rev2023.3.3.43278. However, I don't think I have used anything that is not available in Python 3.9, and the code can be trivially made to work with at least Python 3.8. Given a string, find the shortest possible string which can be achieved by adding characters to the end of initial string to make it a palindrome. Given a sorted array of integers a, find an integer x from a such that the value of. It's a basic minesweeper game in terminal. After all the cells with zero value and their neighbours are displayed, we can move on to the last scenario. As we mentioned before, there are two kinds of player input : In a normal kind of move, the row and column number are mentioned. Is there a solutiuon to add special characters from software and how to do it. It means that throughout the years your balance would be: Thus, it will take 3 years for your balance to pass the threshold, which is the answer. The row and column numbers displayed along with the grid are helpful for our input system. Two cells are called neighboring if they share at least one corner.'''. Upper or lower case, it shouldn't matter. You are playing an RPG game. PEP8: PEP8 talks about using snake_case for variable/function naming (whilst class naming is CamelCase) and a few other things. Does Counterspell prevent from any further spells being cast on a given turn? It appears that MineBoard is not actually a board of mines. topic page so that developers can more easily learn about it. one with mines (and mine counts, for convenience) and one layer that shows if the position has been revealed or flagged. The objective is to fill a 9 9 grid with digits so that each column, each row, and each of the nine 3 3 sub-grids that compose the grid contains all of the digits from 1 to 9. I hope the other answers as well as mine are enough to give you lots to study before your next interview. For instance, it would allow you to flag already revealed positions, or maybe call setMine after the setup stage. // We can obtain b from a by swapping 2 and 1 in b. Additionally, you don't need to generate this list yourself, you can use random.sample: You're using this method in several places inside loops. Some obvious classes for a Minesweeper game would include for example Game, Board and Tile. Note that there are only two items and you can't bring more than one item of each type, i.e. Do read comments as they explain a lot and also every block of code. The bishop has no restrictions in distance for each move, but is limited to diagonal movement. It looks like you are missing an abstraction, probably something like a Cell (which could be a namedtuple or a dataclass). All possible sums of 2 consecutive elements are: [input] array.integer inputArray A positive integer representing the nightly growth. xem xt . This comment is problematic for many reasons. You are allowed only to make jumps of the same length represented by some integer. To learn more, see our tips on writing great answers. You are given an array of desired filenames in the order of their creation. I wish you the best of luck with the interviewing process and hope you get the job. It is guaranteed that you've been riding for less than a day (24 hours). F-strings: Python 3.6 and later have this capability; f-strings can make reading print statements much easier. Does Python have a string 'contains' substring method? Does a barbarian benefit from the fast movement ability while wearing medium armor? We just published a Python course on the freeCodeCamp.org YouTube channel that will teach you how to code Minesweeper using the tkinter library. I like this, and the fact that you use a separate call to print the board. CodeSignal - Arcade - Intro - JS - Minesweeper Raw Minesweeper.js function minesweeper(matrix) { let height = matrix.length; let width = matrix[0].length; let outArray = Array.from(Array(height), () => new Array(width)); let mines = 0; for(let i = 0; i < height; i++) { for(let j = 0; j < width; j++) { mines = 0; if(i > 0) { What Is the Difference Between 'Man' And 'Son of Man' in Num 23:19? Regardless, thank you for your feedback. Cannot retrieve contributors at this time. Solutions for challenges proposed on CodeFights.com. Calculating probabilities from d6 dice pool (Degenesis rules for botches and triggers). CodeSignal (former CodeFights) https://app.codesignal.com/ Problems from Arcade, Challenges and battles against Bots with my solutions in Python. I know that represent everything in just one single number makes things much more complex here. It's so bad you want to sneak out, which is quite simple, especially since the exit is located right behind your row to the left. All you know thanks to the bike's timer is that n minutes have passed since 00:00. The rate of increase. Given a ticket number n, determine if it's lucky or not. Starting off with some arrangement of mines we want to create a Minesweeper game setup. A tag already exists with the provided branch name. I love how you help to suggest some other names for my variables. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Thank you in advance. [input] integer rate [input] string inputString Refactoring covers not only lines of code into a function, but of data objects into different structures. I always struggle to name things while coding. The neighbours function is a recursive one, solving our problem. Thus, the longest call you can make is 1 + 9 + 4 = 14 minutes long. I've always find it incredulous that comments are discouraged in a blanket fashion. When this count is equal to the total cells, except those containing mines, then the game is regarded as over.
