"Minesweeper" - Codesignal #24 - JAVA Solution - YouTube 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 largest integer divisible by 3 and not larger than 10 is 9. The idea to have one board with an integer to represent states is a nice idea. Ratiorg got statues of different sizes as a present from CodeMaster for his birthday, each statue having an non-negative integer size. The best answers are voted up and rise to the top, Not the answer you're looking for? They should really have more intention-revealing names. Something like: MineBoard(width, height, num_mines) and self.cellsToOpen = width * height - num_mines is much easier to understand. A constraint satisfaction problem has a few parts: A set of variables. 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. This Is How To Create A Simple MineSweeper Game In Python! MathJax reference. How can I delete a file or folder in Python?

It could access Cell objects and -- when passed slices --- could even return an iterable over the Cells. [input] array.string inputArray For one, it is placed in an awkward sport, in the middle of the class. Any solution is necessarily going to have to look at every cell in the board, which means it can never possibly be faster than O(n). If, instead, I copy&paste the code into my editor, even during the "paste" operation, it already starts automatically applying fixes, and I only get 139 Errors, 30 Warnings, and 21 Infos.

Variable Naming: line 21 states self.cellsToOpen = w * h - k, but the comment says # Create a new board with size w x h, and the caller is MineBoard(w, h, m). Object Oriented Programming with Python - Code a Minesweeper Game The trickiest part of creating the game is managing this scenario. The domain name part of an email address may only consist of letters, digits, hyphens and dots. I could guess the w and h, but how could a caller know that k is the number of mines? 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.
