(243)
Rate
Write a function to compute the determinant of an n x n matrix with diagonal entries equal to an integer m and other entries equal to 1. For example, a 4x4 matrix with 3s on the diagonal and 1s elsewhere has a determinant of 48, and a 6x6 matrix with 4s on the diagonal and 1s elsewhere has a determinant of 2187. Return the answer as a character string, and see the test suite for forbidden functions.
