Given a 4 x 4 matrix, we have to interchange the elements of first and last row and show the resulting matrix.
Input : 3 4 5 0 2 6 1 2 2 7 1 2 2 1 1 2 Output : 2 1 1 2 2 6 1 2 2 7 1 2 3 4 5 0 Input : 9 7 5 1 2 3 4 1 5 6 6 5 1 2 3 1 Output : 1 2 3 1 2 3 4 1 5 6 6 5 9 7 5 1
The approach is very simple, we can simply swap the elements of first and last row of the matrix inorder to get the desired matrix as output.
Below is the implementation of the approach :
9 9 7 7 4 7 6 5 3 2 1 8 8 9 7 6
