Determinant filled with unit and inverse.
I thought of this problem cuz, I was doing some problem and saw a matrix filled with only one's and thought what happens if they get inversed.

Given a (an) $n\times n$ matrix,
whose entries are real numbers. Either 1 or -1, what are the different values that can be obtained?
