I would certainly perform a clear split between setting up the board and playing the game. Jim from JimShapedCoding developed this course. Before creating the game logic, we need to design the basic layout of the game. A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. It mixes responsibilities of creating the string representation and printing it. Entry point: As we're writing a script for execution, and not as a library, the entry point if __name__ == "__main__": should be used. 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. '''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. A non-negative integer representing the heaviest weight you can lift with your left arm. Note: The randint function can only be used after importing the random library. 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. rev2023.3.3.43278. Therefore, Minesweeper has a provision of using flag to mark the cells, which we know contains a mine. The split could be virtual (just private methods called when setting up the board, otherwise not separated) or explicit (a separate builder class). Write and run code in 50+ languages online with Replit, a powerful IDE, compiler, & interpreter. Does Python have a string 'contains' substring method? I hope the other answers as well as mine are enough to give you lots to study before your next interview. In particular, it represents two totally different concepts: a map / board, and a game. For each cell in the grid, we have to check all adjacent neighbours whether there is a mine present or not. 'E' represents an unrevealed empty square, 'B' represents a revealed blank square that has no adjacent mines (i.e., above, below, left, right, and all 4 diagonals), digit ( '1' to '8') represents how many mines are adjacent to this revealed square, and 'X' represents a revealed mine. 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? Correct variable names consist only of Latin letters, digits and underscores and they can't start with a digit. To learn more, see our tips on writing great answers. When this count is equal to the total cells, except those containing mines, then the game is regarded as over. The region and polygon don't match.

As I said, using exceptions as normal control is a bad idea in most languages, python being an exception. A book called "Code Complete" can be useful in learning different patterns of common mistakes made by programmers, I recommend grabbing a copy. // The arrays are equal, no need to swap any elements. 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. sign in This abstraction would also allow us to move some of the methods out of MineBoard. However, any recommendations for optimisation are welcome! 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.
