/*
Matrix is a 2-D Array.
The transpose of a matrix is formed by turning all the rows of a given matrix into column and vice-versa.
The code gives output as Transpose of a given matrix.

Sample Output:

Enter the number of rows in matrix = 3
Enter the number of columns in matrix = 3

Enter the values in matrix  -->
1   2   3
4   5   6
7   8   9

Transpose of a matrix is -->
