"""
Transpose of a matrix is a matrix obtained by changing rows to columns and columns
to rows.In other words, transpose of Arr[][] is obtained by changing Arr[i][j] to Arr[j][i].
The below program finds transpose of matrix[][] and stores the result in result[][]

Sample I/O :

Enter the number of rows : 3
Enter the number of columns : 3
Enter the entries rowwise:
1 2 3

The Transpose of the matrix is
1 4 7
