Given a matrix of custom size the task is to generate the transpose of original matrix.

To get the transpose of a matrix we either convert each row to column or convert each column to row.

Example: Consider a matrix

6	4	7
3	2	8

We will change the first row to first column.

→

Similarly change the second row to second column.

→

Hence we get transpose of original matrix as

6	3
4	2
7	8

Print the original matrix along with the transpose of the matrix.

        System.out.print("Enter no.of rows: ");
        row=sc.nextInt();
        System.out.print("Enter no.of columns: ");
        col=sc.nextInt();
        int ar[][]=new int[row][col];
        int tr[][]=new int[col][row];
