It applies game mechanics that offer developers of all skill levels online computer programming challenges for both instructional and recruiting purposes. I like the way the status is explicitly kept using the enum; it makes everything that more easy to follow. 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. def minesweeper (array): # Vertical iterations for lineIndex in range (len (array)): line = array [lineIndex] outputLine = [] # Horizontal iterations for cellIndex in range (len (line)): # Check cell content if (line [cellIndex] == "O"): northIndex = lineIndex - 1 eastIndex = cellIndex - 1 southIndex = lineIndex + 1 westIndex = cellIndex + 1 It's still O(n) time with respect to array, though; it's not really possible to improve on that. The terminal becomes crowded as we keep on printing stuff on it. I did not manage to finish the game in 1 hour at that time, so now I have written it again after the interview. 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. February 7, 2022 .

I was trying to make that cautionary point. The neighbours function is a recursive one, solving our problem. You can pass any iterable to the list constructor to create a list: You import pdb but never use it. It is guaranteed that parentheses form a regular bracket sequence. It's recommended to use them when writing any string statement that contains variables. All of them are fully functional. But I honestly don't see why they exist at all, in that case. 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.
