You can initialize a result matrix with a zero on "O" cells and "X" on the mine positions. It should probably be part of the class documentation proper, i.e. The results string should not contain any parentheses. Is it a bug? 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. . This becomes a bit troublesome if you also allow "virtual clicks", as we find out later in the method. As indicated in other questions: using a position type would make sense, e.g. For one, it is placed in an awkward sport, in the middle of the class.

Each child will eat 3 pieces. So the answer is 9. Do you see how this might be confusing to someone that is reading your code? the first minute costs 3 cents, which leaves you with 20 - 3 = 17 cents; the total cost of minutes 2 through 10 is 1 * 9 = 9, so you can talk 9 more minutes and still have 17 - 9 = 8 cents; each next minute costs 2 cents, which means that you can talk 8 / 2 = 4 more minutes. It looks like you are missing an abstraction, probably something like a Cell (which could be a namedtuple or a dataclass). In particular, I have type checking turned on, and almost 130 of the Errors are from Pylance complaining it can't fully determine the static type of some variable, parameter, or function. Any solution is necessarily going to have to look at every cell in the board, which means it can never possibly be faster than O(n). We need to set up the positions of the mines randomly, so that the player might not predict their positions. If there is no such integer, return -1 instead.

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". Generally the code shows a consistent style, so in that regard I think it looks good. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2.
