create python program with data structures: Billy Wiccan still likes arts and crafts! He has a paper containing an $nn$ grid of numbers, and he wants to check how the grid looks from many different angles. For example, here is a $44$ grid.

If Billy rotates the grid $90$ degrees clockwise, he gets the following.

If he instead rotates the grid $90$ degrees counter$-$clockwise, he gets the following.

The input are as follows. The first line of input contains an integer $)n(100.$ This is followed by the grid, given as $n$ lines, each line containing $n$ space$-$separated integers. The grid is followed by a single line containing either clockwise or counter$-$clockwise.

Output the grid, rotated in the specified direction.
