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

The minor of an element ai,j of a matrix A is the determinant of the matrix obtained by removing the row and column to which the given element ai,j belongs. Thus, if the original matrix has four rows and 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 Iand j. Assume that the corresponding function prototype is

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