A better description for this problem can be found at http://joonprogramming.blogspot.com/2016/04/google-code-jam-qualification-round-1a_17.html We have to find an NXN matrix, without repeating numbers at any row or column that must be ordered. And we have 2*N-1 strips of scrambled numbers, which can be rows or columns. The problem is to find what the missing strip is (notice that a NXN matrix has 2*N strips).

Get the length of a given vector
Are all the three given point in the same line?
