The largest integer divisible by 3 and not larger than 10 is 9. For instance, it would allow you to flag already revealed positions, or maybe call setMine after the setup stage. As pixel's value is an integer, all fractions should be rounded down. I have written this code in Python 3: def arrayChange (inputArray): original = inputArray [:] count = 0 if len (set (inputArray)) == 1: return ( (len (inputArray)-1)**2 + (len . An n-interesting polygon is obtained by taking the n - 1-interesting polygon and appending 1-interesting polygons to its rim, side by side. It is therefore quite easy to move the board into an invalid state or to make invalid moves. When this count is equal to the total cells, except those containing mines, then the game is regarded as over.
