Reverse rows

Given an grid of integers, you are asked to reverse each row of that grid and print both the initial and the final grid.
The first line of the input contains two integers - the height of the grid h and the width of the grid w. The next h lines contain w integers.
The program should print 2 grids each with h rows, which have w integers. The first grid should be the initial one, while the second grid should have the rows reversed.
Input
3 4
10 20 30 40
11 21 31 41
12 22 32 42

Output
10 20 30 40
11 21 31 41
12 22 32 42
