Note: If you end up using an additional array, you will only receive a partial score.

Problem Constraints

1 <= N <= 1000

Input Format

First argument is a 2D matrix A of integers

Output Format

Rotate the given 2D matrix A.

Example Input

Input 1:

``` [
[1, 2],
[3, 4]
]```

Input 2:

``` [
[1]
]```

Example Output

Output 1:
