Find centralized, trusted content and collaborate around the technologies you use most. recursive (d) /* get the value of one lower d*/ - ( (mainarray [rownumber + ~- (d/3)] || 0) I was given 15 minutes to solve this in a coding challenge, and still can't figure out for the life of me how someone would have approached this. In particular, I have type checking turned on, and almost 130 of the Errors are from Pylance complaining it can't fully determine the static type of some variable, parameter, or function. It's a basic minesweeper game in terminal. one with mines (and mine counts, for convenience) and one layer that shows if the position has been revealed or flagged. codesignal-solutions Duplicated code: I see multiple calls to self.isValidCell and other functions inside the class. [input] array.integer a of the docstring. 01-23-45-67-89-AB). Example. 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. If there is no such integer, return -1 instead. The difference between the phonemes /p/ and /b/ in Japanese, Styling contours by colour and by line thickness in QGIS. Here you can look at several examples of correct and incorrect email addresses. If you want to minimize space usage, use a generator to join each line of output rather than allocating a list. Here's my proposal: (I like using dataclasses for things like this, but of course there are plenty of other options, like attrs or a plain Python class!). // All rearrangements don't satisfy the description condition. Factories, factory methods and/or private methods could play a role here. I appreciate any ideas. The players motive behind this move is to unlock a cell that does not contain a mine.

Instead, this method should be split into two methods. [input] array.integer a Given a sorted array of integers a, find an integer x from a such that the value of. It can be done by 'import os' at the start of the program. Generally the code shows a consistent style, so in that regard I think it looks good. python3 minesweeper.py.

Given an array of strings, return another array containing all of its longest strings. 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. Does Python have a string 'contains' substring method? The function 'show_mines()' is responsible for it. Generally speaking, comments are a code smell.

[input] array.array.boolean matrix 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. In the given example all boundary pixels were cropped, and the value of the pixel in the middle was obtained as (1 + 1 + 1 + 1 + 7 + 1 + 1 + 1 + 1) / 9 = 15 / 9 = rounded down = 1. A set of constraints on these variables that must be satisfied. There is absolutely no reason to use Python 2 for new code in 2021. //Any swap of any two elements either in a or in b won't make a and b equal.

If a[i] = -1, then the ith position is occupied by a tree. 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 . This is important because when you put out code for others to use, if they begin accessing/modifying internal class variables and you release a new version with modified internals, it will break their implementation. Check out the image below for better understanding: [input] array.integer inputArray No effort is needed to handle this case, as all we need to do is alter the displaying value. 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".
