Line 8 -- initializes the first row of the final output matrix with all zeros. Line 15 -- calculates the product at the intersection of the k-th row and k-th column and adds the element to the output matrix (element-wise multiplication) Line 16 -- actually assigns the result of line 15 to the respective cell of the matrix
