Gameplay Demo Aftermath of few hours of creating a game of Minesweeper. We will walk through how to create a board, plant the bombs, and dig recursively. MathJax reference. Connect and share knowledge within a single location that is structured and easy to search. It seems that a click is also opening mines around the clicked location. Does Counterspell prevent from any further spells being cast on a given turn? Why are physically impossible and logically impossible concepts considered separate in terms of probability? I think this may be a method that got expanded and never renamed. Given a string, find out if its characters can be rearranged to form a palindrome. An n-interesting polygon is obtained by taking the n - 1-interesting polygon and appending 1-interesting polygons to its rim, side by side. I'd have to print out the board to understand printLayout fully, but that's OK. (I've taken the liberty of converting all identifiers to PEP8 style.). For matrix = [[true, false, false], [false, true, false], [false, false, false]] the output should be . I would expect that a method called printLayout prints just the layout. Rules are super simple: We take as input a grid of where the mines are, and we output a grid where each cell represents the number of mines explicitly around it. Solutions for challenges proposed on CodeFights.com. You fixed the bad borders, but OP had a simple if, where you use exception handling as "regular" code logic. [input] integer deposit If there is no such integer, return -1 instead. All that said, after I concluded the review I understood the class design and would be able to alter it. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. If you want to minimize space usage, use a generator to join each line of output rather than allocating a list. Each year the amount of money on your account increases by 20%. It took me a few seconds to understand that it required an upper-case F to correctly flag a tile. Return an array of names that will be given to the files. minesweeper codesignal The Blog. We need to set up the positions of the mines randomly, so that the player might not predict their positions. Rectangular matrix of the same size as matrix each cell of which contains an integer equal to the number of mines in the neighboring cells. PyQt5. The winner of the election must secure strictly more votes than any other candidate. I'm doing codefight's challange: minesweeper. Single mine flagging: In typical minesweeper, even when there is one mine remaining (flagged or unflagged), tiles that are unclicked still require clicking. Python 2 is no longer supported since 1 January 2020 (i.e. Is it possible to rotate a window 90 degrees if it has the same length and width? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. One which just creates the string representation of the board, and a second one which prints it. Given array of integers, remove each kth element from it. He knows a lot about art and his advice is usually good, but not this time: the performance turned out to be awfully dull. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Your MineBoard class explicitly inherits from object. Thank you for taking your time ! 01-23-45-67-89-AB). Game Loop is a very crucial part of the game. RSA Algorithm: Theory and Implementation in Python. If you are part of a team, you should adapt your style to match the rest of the team. Generating Minesweeper Boards in Python - LVNGD A non-negative integer representing the heaviest weight your friend can lift with his or her left arm. The player has to prevent himself from landing on a mine with the help of numbers in the neighbouring tiles. I like the way the status is explicitly kept using the enum; it makes everything that more easy to follow. How can I access environment variables in Python? A non-negative integer representing the heaviest weight you can lift with your left arm. Note: The actual value for a mine is stored as -1, whereas the values stored for display, denote the mine as 'M'. To learn more, see our tips on writing great answers. python3 minesweeper.py. 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. There must be something in that :). .strip(): Normally .strip() is chained at the end of a string where the data can have extraneous spacing, but this one is your own string. You signed in with another tab or window. Game). As we know, keeping track of mines without any indicator can be difficult. Factories, factory methods and/or private methods could play a role here. [input] array.array.boolean matrix The players motive behind this move is to unlock a cell that does not contain a mine. 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. How can I access environment variables in Python? Mine Sweeper game implementation using Python program. The first item weighs weight1 and is worth value1, and the second item weighs weight2 and is worth value2. Is it correct to use "the" before "materials used in making buildings are"? Oh well, a bit of unfairness never hurt :). true if symbol is a digit, false otherwise. For classes, be aware of what variables which are internal/private, and place an underscore _ before them. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Non-empty array of positive integers. Movie with vikings/warriors fighting an alien that looks like a wolf with tentacles. A few superficial things: Games like this are perfect for object oriented code. So it definitely passed that test. I'd use regular expressions here, if just to weed out invalid commands. This repository includes my solutions for the arcade challenges in CodeSignal. Your code is all bunched up together. CodeSignal-Solutions/24 - minesweeper.py at master - GitHub A ticket number is considered lucky if the sum of the first half of the digits is equal to the sum of the second half. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, Python: slicing a multi-dimensional array. What is the total maximum value of the items you can take with you, assuming that your max weight capacity is maxW and you can't come back for the items later? Classes exposing private attributes as public: Proper OOP ensures that the internals of how classes achieve their magic are hidden. Cannot retrieve contributors at this time 29 lines (28 sloc) 1.04 KB Raw Blame Edit this file E recursive (d) /* get the value of one lower d*/ - ( (mainarray [rownumber + ~- (d/3)] || 0) So, for example, there is an obvious way that looks like it should work, but you tried it and it didn't work for a non-obvious reason. [input] integer k Check if all digits of the given integer are even. CodeSignal/Arcade/Intro/Intro - minesweeper.java Go to file Cannot retrieve contributors at this time 36 lines (35 sloc) 1.17 KB Raw Blame int [] [] minesweeper (boolean [] [] matrix) { //either this or a lot of ifs (ArrayIndexOutOfBoundsException MADNESS) int [] [] out = new int [matrix.length] [matrix [0].length]; CodeSignal is a skills-based assessment platform whose mission is to discover, develop and promote technical talent. Non-empty string consisting of lowercase English characters. def minesweeper (array): # Vertical iterations for lineIndex in range (len (array)): line = array [lineIndex] outputLine = [] # Horizontal iterations for cellIndex in range (len (line)): # Check cell content if (line [cellIndex] == "O"): northIndex = lineIndex - 1 eastIndex = cellIndex - 1 southIndex = lineIndex + 1 westIndex = cellIndex + 1 We want to know when the height of the plant will reach a certain level. Are you sure you want to create this branch? [input] integer n [input] array.string inputArray My code is GPL licensed, can I issue a license to have my code be distributed in a specific MIT licensed project? CodeSignal (former CodeFights) https://app.codesignal.com/ Problems from Arcade, Challenges and battles against Bots with my solutions in Python. The link to the post with the source code. Here's just a couple that my editor flagged: Note that, if we ignore the afore-mentioned undefined types, then the naming accounts for a vast majority of the remaining issues my editor reports. I could guess the w and h, but how could a caller know that k is the number of mines? No description, website, or topics provided. Define a word as a sequence of consecutive English letters. At least I presume it is a margin of sorts. [input] string s A simple Minesweeper in Python - Code Review Stack Exchange You are given an array of positive integers - the weights of the people. If a[i] = -1, then the ith position is occupied by a tree. // We can obtain b from a by swapping 2 and 1 in b. Correct variable names consist only of Latin letters, digits and underscores and they can't start with a digit. It is guaranteed that the parentheses in s form a regular bracket sequence. rev2023.3.3.43278. It is also a game of minesweeper. Funny that we came to the dual layer / dual classes approach seperately. Given a ticket number n, determine if it's lucky or not. How to Format a Number to 2 Decimal Places in Python? Write and run code in 50+ languages online with Replit, a powerful IDE, compiler, & interpreter. A non-empty rectangular matrix consisting of boolean values - true if the corresponding cell contains a mine, false otherwise. Without this information, the recursion will continue perpetually. So, your class declaration should just be. I don't know who can finish it that fast with the fixes. You wrote that you're going for coding interviews, so I'll focus on various aspects that will be looked at by interviewers rather than pieces of code which other respondents already have. Code Review Stack Exchange is a question and answer site for peer programmer code reviews. Are you sure you want to create this branch? Aftermath of few hours of creating a game of Minesweeper. You can initialize a result matrix with a zero on "O" cells and "X" on the mine positions. Given array of integers, find the maximal possible sum of some of its k consecutive elements. And then in play, the two calls to game.print_layout() can simply be replaced by print(game). This is done by: The function check_over(), is responsible for checking the completion of the game. A square grid is rather easy to create using Python by: The grid displayed in each iteration resembles the following figure: The 'M' symbol denotes the presence of a mine in that cell. This method uses higher level functions to detect the state of a position, but then uses += 1 to set the state. They should be called _ to make clear that they are deliberately ignored: All the elifs can just be ifs, since in all of the conditionals in this method, we either exit the method or the conditional was false. is the smallest possible (here abs denotes the absolute value). We just published a Python course on the freeCodeCamp.org YouTube channel that will teach you how to code Minesweeper using the tkinter library. A set of constraints on these variables that must be satisfied. Note that PEP8 mandates two lines after classes, one line after methods and functions. The terminal becomes crowded as we keep on printing stuff on it. It should probably be part of the class documentation proper, i.e. Given an array of integers, replace all the occurrences of elemToReplace with substitutionElem. [input] integer yourLeft A character which is either a digit or not. He scanned the check of the items he bought and gave the resulting string to Ratiorg to figure out the total number of purchased items. 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. Mostly, comments should not exist: The only acceptable thing for a comment is to explain why the code does something in a specific non-obvious way. It's clear that an enum for state and data is needed per tile, as well as the tile having the capability of call-backs into the board say when a mine was triggered. Obviously I've read through your code several times and I understand what your code does - but I shouldn't have to read it more than once to fully comprehend the statements. moves required to obtain a strictly increasing sequence from the input. Generally speaking, comments are a code smell. It mixes responsibilities of creating the string representation and printing it. @KennyOstrom I don't see an issue with it. using " instead of '). 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. rev2023.3.3.43278. Several people are standing in a row and need to be divided into two teams. Ideally, you would add a link to the pull request / code review / bug ticket where this issue is discussed in greater detail and maybe a link to a wiki page with a detailed explanation. You can t. The rate of increase. Recursion is a programming tool in which the function calls itself until the base case is satisfied. Returning values from functions that aren't used - but as a way to exit the function, Not using a proper data structure to represent the tiles and their behaviour, Spelling/Grammar mistakes in the information presented to the user, Game not acting properly when flagging a single mine (3x3, 1 mine) - finishing automatically, Game not acting properly when flagging a single mine (5x5, 1 mine) due to lower-case f. Asking for help, clarification, or responding to other answers. 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. When I save your code into a file and open the file in my editor, I get a whopping, Now, to be fair, a lot of these are duplicates, because as I mentioned, I have multiple linters and analyzers set up. It looks like you are missing an abstraction, probably something like a Cell (which could be a namedtuple or a dataclass). Instead, this method should be split into two methods. Here's my proposal: (I like using dataclasses for things like this, but of course there are plenty of other options, like attrs or a plain Python class!). Build a minesweeper clone in Python, using PyQt5 For example, as mentioned, if I simply save your code into a file and open that file in an editor, I get 157 Errors, 44 Warnings, and 21 Infos.
