They should really have more intention-revealing names. You cannot let this ruin your reputation, so you want to apply box blur algorithm to the photo to hide its content. Solutions for challenges proposed on CodeFights.com. The winner of the election must secure strictly more votes than any other candidate. | by Leonard Yeo | The Startup | Medium 500 Apologies, but something went wrong on our end. 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. Assuming that your hunch is correct, decode the message. 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. String consisting of 2 letters - coordinates of the knight on an 8 8 chessboard in chess notation. In particular, I have type checking turned on, and almost 130 of the Errors are from Pylance complaining it can't fully determine the static type of some variable, parameter, or function. Here you can look at several examples of correct and incorrect email addresses. To review, open the file in an editor that reveals hidden Unicode characters. Making statements based on opinion; back them up with references or personal experience. 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. After some thought, your first guess is that each consecutive 8 bits of the code stand for the character with the corresponding extended ASCII code. 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. Then you can add a comment explaining that you are specifically using solution B even though it looks like much simpler solution A should also work, but it actually doesn't work because of issue X. Return an array of two integers, where the first element is the total weight of team 1, and the second element is the total weight of team 2 after the division is complete. Factories, factory methods and/or private methods could play a role here. You can t. After we land on a cell with mine, we need to display all the mines in the game and alter the variable behind the game loop. Is it plausible for constructed languages to be used to affect thought and control or mold people towards desired outcomes? Generally I would make those specific to the class; you need this to understand most of the methods in it anyway. I always struggle to name things while coding. It could access Cell objects and -- when passed slices --- could even return an iterable over the Cells. If you want to minimize space usage, use a generator to join each line of output rather than allocating a list. Making statements based on opinion; back them up with references or personal experience. 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. rev2023.3.3.43278. For one, it is placed in an awkward sport, in the middle of the class. A positive integer representing the nightly growth. You have a string s that consists of English letters, punctuation marks, whitespace characters, and brackets. Given an integer product, find the smallest positive (i.e. CodeSignal-Solutions/24 - minesweeper.py Go to file Go to fileT Go to lineL Copy path Copy permalink This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. This means we need to check at 8 spots for each cell: Top left, Top Middle, Top Right, Middle Right, Middle Left, Bottom Left, Bottom Middle, and Bottom Right. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? 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. Initially, plant is 0 meters tall. Each night that plant's height decreases by downSpeed meters due to the lack of sun heat. Each year the balance increases by the rate percent of the current sum. Given an array of integers, find the maximal absolute difference between any two of its adjacent elements. It applies game mechanics that offer developers of all skill levels online computer programming challenges for both instructional and recruiting purposes. The function 'show_mines()' is responsible for it. Return an array of names that will be given to the files. Also, mentioning that you know one or two patterns during your interview (you should know them well enough to write them on a whiteboard) can make you stand out from the crowd. This goes entirely unexplained in the code. Imports: Unused imports hint that perhaps you're not fully aware of all the actions of your scripts? I like the way the status is explicitly kept using the enum; it makes everything that more easy to follow. Cheers! 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. Instead of looping unnecessarily over out-of-bound cells, try instead adjusting the range boundaries: This is just a spur-of-the-moment idea, but you could implement __getitem__ for the MineBoard class. If there are several possible answers, output the smallest one. Use MathJax to format equations. Just a minor thing, the "strip" function I used is on the input from the user, not the 'instruction' itself. Since two files cannot have equal names, the one which comes later will have an addition to its name in a form of (k), where k is the smallest positive integer such that the obtained name is not used yet. Upper or lower case, it shouldn't matter. recursive (d) /* get the value of one lower d*/ - ( (mainarray [rownumber + ~- (d/3)] || 0) Instead, this method should be split into two methods. The neighbours function is a recursive one, solving our problem. There are three different scenarios: The game is finished as soon as the player selects a cell having a mine. The first one should probably just be MineBoard's __str__ method, and the second one should probably be part of the game logic rather than the board logic. Given values experience, threshold and reward, check if you reach the next level after killing the monster. Given an array of integers, replace all the occurrences of elemToReplace with substitutionElem. This way, the main entry point will only be automatically executed if the module is run as a script, but not if it is imported: Since you intend to run this as a script, it should have a shebang line, something like this: Note: In order to make this answer useful for future readers, I have mostly assumed Python 3.10, which is about to be released soon. Ticket numbers usually consist of an even number of digits. It is guaranteed that the first two characters, as well as the last two characters, are digits. A string consisting of English letters, punctuation marks, whitespace characters and brackets. This Is How To Create A Simple MineSweeper Game In Python! Your MineBoard class explicitly inherits from object. First you create a list of indices, set the mines and then.. setAdjacentMines - why? Refresh the page, check Medium 's site. It should probably be part of the class documentation proper, i.e. It is also a game of minesweeper. Minesweeper is a single-player game in which the player has to clear a square grid containing mines and numbers. 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). There is absolutely no reason to use Python 2 for new code in 2021. The first item weighs weight1 and is worth value1, and the second item weighs weight2 and is worth value2. I hope the other answers as well as mine are enough to give you lots to study before your next interview.

Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. All pixels at the edges are cropped. Given a string, output its longest prefix which contains only digits. After taking care of these issues, the cell is flagged for a mine. Do you see how this might be confusing to someone that is reading your code? This is especially true for environments that allow for reordering or refactoring of methods. 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.. Determine if the given character is a digit or not. This becomes a bit troublesome if you also allow "virtual clicks", as we find out later in the method. Check if the given string is a correct time representation of the 24-hour clock. The first 8 characters of the code are 01001000, which is 72 in the binary numeral system. Remove the import. using " instead of '). Example. Tiles data structure: Each tile on the board has multiple states (hidden/revealed/flagged) and data (empty/has mine) which is complicated behaviour. I don't exactly get what it is supposed to do at first glance, even after looking at the conventions. The number of flags does not exceed the number of mines. I am not a big fan of mixing I/O and computation. There is not much in the game-logic of Minesweeper. This can be done by: Note: There is a need to import the os library, before using this feature. Connect and share knowledge within a single location that is structured and easy to search. The standard input involves the overall functioning of the game. 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. A non-empty array. This is not a code review site, so this question is off-topic, but your solution is not bad. In this video, we will implement a game of minesweeper in Python! We keep doing this until we get the said number of mines. Given a divisor and a bound, find the largest integer N such that: It is guaranteed that such a number exists. sign in It is done by writing 'import random' at the start of the program. Enum for GameStatus but then not using the same logic with tile values? 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. Is a PhD visitor considered as a visiting scholar? If two or more candidates receive the same (maximum) number of votes, assume there is no winner at all. Sometimes, you have 1 blank line after the function. Work fast with our official CLI. The lifeline of this program is the recursive function - playMinesweeperUtil () This function returns a true if the user steps/clicks on a mine and hence he loses else if he step/click on a safe cell, then we get the count of mines surrounding that cell. Find centralized, trusted content and collaborate around the technologies you use most. Find the leftmost digit that occurs in a given string. This version is a little different to the others out there in that it's supposed to start by asking the user how big the grid, then how many mines to insert. That one was expected after seeing isOver being defined. Chess Notation: Given some integer, find the maximal number you can obtain by deleting exactly one digit of the given number. So we have w h k x m variables here. 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 Please note the use of the exception (that was the hint regarding the "x"s). Does Python have a ternary conditional operator? But I honestly don't see why they exist at all, in that case. However, it seems that it prints the entire board & board state. This can be done by: In the code, we choose a random number from all possible cells in the grid. python. Given an array of integers, find the pair of adjacent elements that has the largest product and return that product.ding the year 100, the second - from the year 101 up to and including the year 200, etc. You are given an array of desired filenames in the order of their creation. We count the number of cells, that are not empty or flagged. It can happen out of bad luck or poor judgment. I get IndexError with this code. Given an integer n, return the largest number that contains exactly n digits. Please Some phone usage rate may be described as follows: You have s cents on your account before the call. To review, open the file in an editor that reveals hidden Unicode characters. 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. This is done by: These values are to be hidden from the player, therefore they are stored in numbers variable. After becoming famous, CodeBots decided to move to a new building and live together. So, your class declaration should just be. Where does this (supposedly) Gibson quote come from? If you are part of a team, you should adapt your style to match the rest of the team. It results in more readable code and a more logical flow than checking the bounds every time. Improve your Python programming skills by coding everyone's favorite Windows 3.1 game: Minesweeper. [input] integer friendsLeft I love how you help to suggest some other names for my variables. It is guaranteed that the parentheses in s form a regular bracket sequence. [input] array.array.integer image The idea to have one board with an integer to represent states is a nice idea. I have written this code in Python 3: def arrayChange (inputArray): original = inputArray [:] count = 0 if len (set (inputArray)) == 1: return ( (len (inputArray)-1)**2 + (len . (probably with a loop that blocks the rest of the code from running). As we can see clearly, any number on the grid denotes the number of mines present in the neighbouring eight cells. Replacing broken pins/legs on a DIP IC package, About an argument in Famine, Affluence and Morality. About an argument in Famine, Affluence and Morality, Euler: A baby on his lap, a cat on his back thats how he wrote his immortal works (origin?). The minimal number of statues that need to be added to existing statues such that it contains every integer size from an interval [L, R] (for some L, R) and no other sizes. PEP8: PEP8 talks about using snake_case for variable/function naming (whilst class naming is CamelCase) and a few other things. I added a remark that only the pop()s should be fixed and offered a 2D slicing as alternative Codefights, minesweeper, python, code almost working, How Intuit democratizes AI development across teams through reusability. The domain name part of an email address may only consist of letters, digits, hyphens and dots. Find the minimal number of moves required to obtain a strictly increasing sequence from the input. How can I delete a file or folder in Python? I'm doing codefight's challange: minesweeper. Always use words that explain to readers what the code does through proper variable names. For any queries, feel free to comment below. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. The description: The border created by "x", as suggested by codefight's user, is to ensure that if mine is at the border of matrix, bomb count won't transfer to the other side. topic, visit your repo's landing page and select "manage topics.". of the docstring. true if the given representation is correct, false otherwise. Why is there a voltage on my HDMI and coaxial cables? The code already explains the "how". Your task is to rearrange the people by their heights in a non-descending order without moving the trees. A positive even integer. "what about, are you this instead?" Asking for help, clarification, or responding to other answers. [input] array.integer a How can I remove a key from a Python dictionary? Given a rectangular matrix containing only digits, calculate the number of different 2 2 squares in it. It seems that a click is also opening mines around the clicked location. I know that represent everything in just one single number makes things much more complex here. On the completion of input process, the row and column numbers are to be extracted and stored in 'r' and 'c'. F-strings: Python 3.6 and later have this capability; f-strings can make reading print statements much easier. All possible sums of 2 consecutive elements are: [input] array.integer inputArray That is unnecessary in Python 3. PyQt5. Using the bike's timer, calculate the current time. Manually raising (throwing) an exception in Python, How to upgrade all Python packages with pip. He knows a lot about art and his advice is usually good, but not this time: the performance turned out to be awfully dull. Given a ticket number n, determine if it's lucky or not. As indicated in other questions: using a position type would make sense, e.g. A minor comment: if you've ever worked with multilingual applications. Thank you in advance. : Comments in the code explaining what the code does when the code expresses this already, Classes exposing private attributes as public, Mixing game logic with board logic (and instantiating the board as. Alternately, you. // There is no one element in this array that can be removed in order to get a strictly increasing, // You can remove 3 from the array to get the strictly increasing sequence [1, 2]. [input] char symbol This objective is achieved using Recursion. I would certainly perform a clear split between setting up the board and playing the game. Use Git or checkout with SVN using the web URL. Since Ratiorg is a bot he is definitely going to automate it, so he needs a program that sums up all the numbers which appear in the given input. output_matrix = [output_matrix [i] [1:len (output_matrix)-1] for i in range (1, len (output_matrix)-1 . On subsequent games, I failed again because of this input-handling problem. @KennyOstrom I don't see an issue with it. 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.
