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). If there is no such integer, return -1 instead. .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. It is therefore quite easy to move the board into an invalid state or to make invalid moves. Learn more about bidirectional Unicode characters. This comment is problematic for many reasons. Can I tell police to wait and call a lawyer when served with a search warrant? Starting off with some arrangement of mines we want to create a Minesweeper game setup. It must be the result of doing many leetcode exercises recently and I just tend to save memory anytime possible. The nature of simulating nature: A Q&A with IBM Quantum researcher Dr. Jamie We've added a "Necessary cookies only" option to the cookie consent popup. to use Codespaces. Asking for help, clarification, or responding to other answers. Ratiorg got statues of different sizes as a present from CodeMaster for his birthday, each statue having an non-negative integer size. The algorithm works as follows: each pixel x in the resulting image has a value equal to the average value of the input image pixels' values from the 3 3 square with the center at x. Another method is to have multiple layers, e.g. mine = False. 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. This algorithm should check if the given grid of numbers represents a correct solution to Sudoku. 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. The player has to prevent himself from landing on a mine with the help of numbers in the neighbouring tiles. Not the answer you're looking for? You are taking part in an Escape Room challenge designed specifically for programmers. CodeSignal is a skills-based assessment platform whose mission is to discover, develop and promote technical talent. Write a function that returns the sum of two numbers. Chess Notation: Given some integer, find the maximal number you can obtain by deleting exactly one digit of the given number. Remove the import. Help him figure out the minimum number of additional statues needed. 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. After taking care of these issues, the cell is flagged for a mine. python3 minesweeper.py. How to show that an expression of a finite type must be one of the finitely many possible values? I love how you help to suggest some other names for my variables. You are given an array of integers. My code is GPL licensed, can I issue a license to have my code be distributed in a specific MIT licensed project? Do read comments as they explain a lot and also every block of code. Given an array of equal-length strings, check if it is possible to rearrange the strings in such a way that after the rearrangement the strings at consecutive positions would differ by exactly one character. 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. So the answer is 9. Your MineBoard class explicitly inherits from object. Is it correct to use "the" before "materials used in making buildings are"? You are given a two-digit integer n. Return the sum of its digits. The best answers are voted up and rise to the top, Not the answer you're looking for? Not the answer you're looking for? A positive integer representing the nightly growth. He may need some additional statues to be able to accomplish that. He has published many popular programming courses both Single mine flagging: In typical minesweeper, even when there is one mine remaining (flagged or unflagged), tiles that are unclicked still require clicking. It looks like you are missing an abstraction, probably something like a Cell (which could be a namedtuple or a dataclass). Is it plausible for constructed languages to be used to affect thought and control or mold people towards desired outcomes? 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. How do I concatenate two lists in Python? How do you get out of a corner when plotting yourself into a corner, Topological invariance of rational Pontrjagin classes for non-compact spaces. You fixed the bad borders, but OP had a simple if, where you use exception handling as "regular" code logic. Ticket numbers usually consist of an even number of digits. You have a string s that consists of English letters, punctuation marks, whitespace characters, and brackets. Sometimes, you use two blank lines between methods, sometimes only one. This abstraction would also allow us to move some of the methods out of MineBoard. Your friend advised you to see a new performance in the most popular theater in the city. Does Python have a string 'contains' substring method? For example, if you pushed your script into the repository, and a code documentor such as Sphinx ran over it, it would freeze because it would start playing the game. Python supports chained comparisons, i.e. 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. All the effort is to be done in setting up the Minesweeper layout. [output] boolean A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. The function is clearly separated into a series of steps: setup, game loop, finish. First you create a list of indices, set the mines and then.. setAdjacentMines - why? Check if the given string is a correct variable name. Refactoring covers not only lines of code into a function, but of data objects into different structures. Use Git or checkout with SVN using the web URL. Generally I would make those specific to the class; you need this to understand most of the methods in it anyway. One which just creates the string representation of the board, and a second one which prints it. A non-negative integer representing the heaviest weight your friend can lift with his or her left arm. You could avoid some math to find the last item by using append, and give no argument to pop. A few superficial things: Games like this are perfect for object oriented code. The game consists of a grid of hidden square cells with mines randomly scattered throughout the board. You can t. In our version of Minesweeper, we will be using the row and column numbers for our input technique. Since he likes to make things perfect, he wants to arrange them from smallest to largest so that each statue will be bigger than the previous one exactly by 1. How can I remove a key from a Python dictionary? If the IDE doesn't highlight these, possibly change your IDE. I think this may be a method that got expanded and never renamed. //Any swap of any two elements either in a or in b won't make a and b equal. And I get the code formatted according to my preferences (e.g. There should be 2 blank lines after a function or class. I don't exactly get what it is supposed to do at first glance, even after looking at the conventions. Thank you for taking your time ! Where does this (supposedly) Gibson quote come from? There was a problem preparing your codespace, please try again. Suitable implementation of __getitem__ left as an exercise for the reader. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. import random. There are a couple of names in your code that could be clearer, for example ip, m, and k. In particular, it seems that the parameter k in __init__, the parameter num_of_mines in allocate_mines, and the local variable m in play mean the same thing, but the parameter k in get_random_pos does not mean the same thing as the parameter k in __init__. Entry point: As we're writing a script for execution, and not as a library, the entry point if __name__ == "__main__": should be used. I know that represent everything in just one single number makes things much more complex here. Check out the image below for better understanding: A non-empty rectangular matrix consisting of boolean values - true if the corresponding cell contains a mine, false otherwise. The two equal numbers are a and c. The third number (b) equals 7, which is the answer. "what about, are you this instead?"
