A good example is a set of code checking every minute "is it now 7am?" 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. Thanks for contributing an answer to Stack Overflow!

It looks like there is an added border on three sides, but no border added on the right. Some rooms are free (their cost is 0), but that's probably because they are haunted, so all the bots are afraid of them. In particular, it represents two totally different concepts: a map / board, and a game. Return an answer as the sum of digits that the digital timer in the format hh:mm would show.

[input] integer n I actually have multiple linters and multiple static analyzers configured in my editor, and they are set up so that they analyze my code while I type, and automatically correct whatever they can auto-correct when I save. 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. [input] array.string inputArray codesignal-solutions Therefore, there must be provision for clearing it constantly. Funny that we came to the dual layer / dual classes approach seperately. 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.

Duplicated code: I see multiple calls to self.isValidCell and other functions inside the class. Learn more about bidirectional Unicode characters. 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. These methods should definitely be private. Tiles data structure: Each tile on the board has multiple states (hidden/revealed/flagged) and data (empty/has mine) which is complicated behaviour. minesweeper1 = mainarray => // an arrow function, that gets the two d array passed !mainarray.some ( (row,rownumber) => row.some ( (field,columnumber) =>//checking the 2d array if some of the fields field //and the magic recursive function is true d-- ? You can pass any iterable to the list constructor to create a list: You import pdb but never use it. over 12.5 years).

You could certainly make a case that OP's code doesn't need comments, but that's not true in general. There are three different scenarios: The game is finished as soon as the player selects a cell having a mine. This method uses higher level functions to detect the state of a position, but then uses += 1 to set the state. For inputArray = [1, 1, 1], the output should be arrayChange (inputArray) = 3. Here you can look at several examples of correct and incorrect email addresses. The last candidate can't win no matter what (for the same reason as the first candidate). Sometimes, you have 1 blank line after the function. 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. Your task is to check by given string inputString whether it corresponds to MAC-48 address or not. We count the number of cells, that are not empty or flagged. Could you please help me to check if my code follows good practices for a game-program ? Aftermath of few hours of creating a game of Minesweeper. | by Leonard Yeo | The Startup | Medium 500 Apologies, but something went wrong on our end. First, the string is divided into the least possible number of disjoint substrings consisting of identical characters, for example, "aabbbc" is divided into ["aa", "bbb", "c"], Next, each substring with length greater than one is replaced with a concatenation of its length and the repeating character, for example, substring "bbb" is replaced by "3b". As indicated in other questions: using a position type would make sense, e.g. I know that represent everything in just one single number makes things much more complex here. Find the longest word from the given string. 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.

The role of vis to keep track of already visited cells during recursion. In general, your solution is working (if you uncomment the line #matrix [x].insert (len (matrix)+2, "x") ), but you are making mistakes in your pop () sequence. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. Are you sure you want to create this branch? An easy way to get to the adjacent positions is to prepare a list of offsets for the 8 neighbouring cells based on the row and column numbers. The row and column numbers displayed along with the grid are helpful for our input system. We use the function countAdjacentMines () to calculate the adjacent mines. For the first example below, the output should be true. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below.

The second candidate can win if all the remaining candidates vote for him (3 + 3 = 6 > 5). I appreciate any ideas. And then in play, the two calls to game.print_layout() can simply be replaced by print(game). 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. I am not a big fan of mixing I/O and computation. You signed in with another tab or window. The bishop has no restrictions in distance for each move, but is limited to diagonal movement. Code Comments: Comments, if used at all, should be a "why you're doing it this way" and not a "how you're doing this". 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). topic, visit your repo's landing page and select "manage topics.". '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.

These items are something you should be aware of when writing Python code. It appears that MineBoard is not actually a board of mines. Given a string, replace each its character by the next one in the English alphabet (z would be replaced by a). Check if all digits of the given integer are even. 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. Note that there are only two items and you can't bring more than one item of each type, i.e. "oh you're not?" Tp ny cha vn bn unicode hai chiu c th c gii thch hoc bin dch khc vi nhng g xut hin di y.
