Program 10 Write a program to declare a matrix A[ ][ ] of order (m * n), where 'm' is the number of rows
and 'n' is the number of columns, such that both m and n are greater than 2 and less than 20.
Allow the user to input positive integers into this matrix. Display the sum of only the boundary
elements of the original matrix.
