Return an answer as the sum of digits that the digital timer in the format hh:mm would show. But more importantly, the reason why it is hard to give it a proper name is that it appears to be doing too much. # game variables.. run = True. First, the string is divided into the least possible number of disjoint substrings consisting of identical characters, for example, "aabbbc" is divided into ["aa", "bbb", "c"], Next, each substring with length greater than one is replaced with a concatenation of its length and the repeating character, for example, substring "bbb" is replaced by "3b". In other words: if we reach the if at all, we know that all the ifs before it were false, because otherwise we would already have returned from the method.

After taking care of these issues, the cell is flagged for a mine. 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. 2-dimensional array of integers representing a rectangular matrix of the building. Not the answer you're looking for? 'E' represents an unrevealed empty square, 'B' represents a revealed blank square that has no adjacent mines (i.e., above, below, left, right, and all 4 diagonals), digit ( '1' to '8') represents how many mines are adjacent to this revealed square, and 'X' represents a revealed mine. (OTOH, it is tremendously helpful if you have them turned on from the start, since you will be immediately notified and can thus avoid letting the count ever get this high.). That was amazing !.
