To learn more, see our tips on writing great answers. I was trying to make that cautionary point. Array of positive integers. One which just creates the string representation of the board, and a second one which prints it. Python famously has a concept of DRY (Don't Repeat Yourself), which means that when you're starting to see multiple calls to a function, or repeating the same lines, that there is an opportunity for refactoring. In the next couple of posts we are going to play Minesweeper in . [input] string inputString The two equal numbers are a and c. The third number (b) equals 7, which is the answer. This algorithm should check if the given grid of numbers represents a correct solution to Sudoku. Single mine flagging: In typical minesweeper, even when there is one mine remaining (flagged or unflagged), tiles that are unclicked still require clicking. We plant the seed at the beginning of a day. How many neighbours of this cell are mines? The user has to clear the grid without setting off any mine. Why are physically impossible and logically impossible concepts considered separate in terms of probability? Non-empty array of positive integers. Rather than doing that, the set_alarm(self, hour, minute) function would spawn a thread which waits for hour/minute and then activates a call-back to the activate_alarm(self) function. You wrote that you're going for coding interviews, so I'll focus on various aspects that will be looked at by interviewers rather than pieces of code which other respondents already have. Note: The actual value for a mine is stored as -1, whereas the values stored for display, denote the mine as 'M'. Find the minimal length of the jump enough to avoid all the obstacles. Tell - Don't Ask: When your code has a lot of if-this, then-that statements in it, it's clear the logic belongs with the data rather than continually asking the data "are you this?" 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.

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. Classes exposing private attributes as public: Proper OOP ensures that the internals of how classes achieve their magic are hidden. okay, I'll do this action then". 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. In my coding interview for a company, I got the question to write a Minesweeper game. If input: Could anyone explain clearly why that's happening? If any of these cells contain a mine, the cell we are checking it for becomes the NUMBER of mines we have just counted. Each child will eat 3 pieces. Then you can use groups 1, 2 and 3 to retrieve the values. For the other grid, the output should be false: each of the nine 3 3 sub-grids should contain all of the digits from 1 to 9. If your code is so complex that you need to explain it in a comment, you should rather try to refactor your code to be less complex so that it needs no explanation. I don't know who can finish it that fast with the fixes. We use the function countAdjacentMines () to calculate the adjacent mines. Before starting the game, the script must provide a set of instructions for the player. 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). 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). Note: The randint function can only be used after importing the random library. 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. Most other languages enforce this by statements such as private and public before their type and variable name. 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. Personally I don't like it when click hides other functionality, I'd put that in a calling function. It's also less prone to bugs. The best answers are voted up and rise to the top, Not the answer you're looking for? You have a string s that consists of English letters, punctuation marks, whitespace characters, and brackets. Given n and firstNumber, find the number which is written in the radially opposite position to firstNumber.

Making statements based on opinion; back them up with references or personal experience. moves required to obtain a strictly increasing sequence from the input. 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__. click is used as a method name. Does Counterspell prevent from any further spells being cast on a given turn? Whether the cell to be flagged is already displayed to the player. It seems that a click is also opening mines around the clicked location. These items are something you should be aware of when writing Python code. The split could be virtual (just private methods called when setting up the board, otherwise not separated) or explicit (a separate builder class). https://puzzlingclarity.com/index.php/2020/06/21/codesignal-arcade-intro-24-minesweeper/If you have questions or w.
