An n-interesting polygon is obtained by taking the n - 1-interesting polygon and appending 1-interesting polygons to its rim, side by side. When this count is equal to the total cells, except those containing mines, then the game is regarded as over. The code already explains the "how". The same applies to the game loop itself, it also has distinct steps. 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 . Your task is to rearrange the people by their heights in a non-descending order without moving the trees. One of the most important parts of any game is sustaining the input method.
