Thanks for taking your time to write such an detail answer. When needing user input, ensure it's specific, that it's limited, and that you give responses to assist the user to provide the correct input, or allow them to exit the stage where they are.This will enable avoiding runtime errors which crash the program (such as IndexError list assignment index out of range which I encountered) and avoid having try/except/finally statements due to limiting possible inputs. A non-empty array of strings of lowercase letters. CodeSignal is a skills-based assessment platform whose mission is to discover, develop and promote technical talent.

A constraint satisfaction problem has a few parts: A set of variables. There are a couple of names in your code that could be clearer, for example ip, m, and k. In particular, it seems that the parameter k in __init__, the parameter num_of_mines in allocate_mines, and the local variable m in play mean the same thing, but the parameter k in get_random_pos does not mean the same thing as the parameter k in __init__. Note: The actual value for a mine is stored as -1, whereas the values stored for display, denote the mine as 'M'. 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. "oh you're not?" 808 minutes mean that it's 13:28 now, so the answer should be 1 + 3 + 2 + 8 = 14. If a[i] = -1, then the ith position is occupied by a tree.
