Enter the size of the matrix: 3 Enter the elements of the matrix: 7 1 3 2 4 1 1 5 1 The entered matrix is: 7 1 3 2 4 1 1 5 1 Determinant of the matrix is 10. Next, we are going to find the determinant of this matrix. The resultant matrix is : 2 2 4 4 Explanation of above program: Let us first take a look at all the variables used in this program: mata, matb and matc: These are three matrices each with a maximum size of 10x10. A C style array "decays" (is implicitly converted) to a pointer to its first element in most situations. 5. N Queens Problem is a famous puzzle in which n-queens are to be placed on a nxn chess board such that no two queens are in the same row, column or diagonal.
