Problem 2225. Three...is a magic number.
Yes it is...
It's a magic number...
To help you get rid of that earworm, here's a new Cody problem. You are given a square matrix containing positive integers. We want to determine if there are three consecutive occurrences of the same number in a row or column. For example:
1 1 1 4 2 3 2 3 4
Should be marked "true" because there are three consecutive ones in the first row. Likewise
5 2 3 5 3 2 5 4 1
should also be marked "true" because there are three consecutive fives in the first column. However:
5 2 3 3 5 2 1 4 5
Is false, as we do not care about the three consecutive fives along the trace of the matrix. The matrix will always be at least 3x3, but they can be larger. Good luck!
