Hello, I need help with my Computer Algorithms homework. All of the questions are based on this algorithm, yet I have no idea what it does. Please help! What does this algorithm do? I know it works with Matrices but I have stared at it long and hard with no results!

Algorithm CS402Test1(A[0..n - 1, 0..n]) // Input: Ann x (n+ 1) matrix A[0..n 1, 0.n] of real numbers for i 0 to n _ 2 do forj fi+ 1 to n - 1 do for k i to n do
