Determinants. The following problems define cofactors and minors of a square matrix; use them to evaluate a determinant.

The minor of an element a(i, j ) of a matrix A is the determinant of the matrix obtained by removing the row and column to which the given element a(i, j ) belongs. Thus, if the original matrix has four rows and four columns, the minor is the determinant of a matrix with three rows and columns. Write a function to compute the minor of a square matrix with four rows and four columns. The input arguments should be the matrix A and the values of i and j . Assume that the corresponding function prototype is

double minor(double a[][4], int i, int j);
