The standard input involves the overall functioning of the game. 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. Given an array of integers, find the maximal absolute difference between any two of its adjacent elements. minesweeper arrayReplace evenDigitsOnly variableName alphabeticShift chessBoardCellColor circleOfNumbers depositProfit absoluteValuesSumMinimization stringsRearrangement extractEachKth firstDigit differentSymbolsNaive arrayMaxConsecutiveSum growingPlant knapsackLight longestDigitsPrefix digitDegree bishopAndPawn isBeautifulString findEmailDomain 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.
