The array of size $n \times m$ is given. Rotate it $90$ degrees clockwise. \InputFile The first line contains two integers $n$ and $m~(1 \le n, m \le 50)$. Each of the next $n$ lines contains $m$ nonnegative integers, not greater than $10^9$ --- it is the array itself. \OutputFile Print the rotated array in the same format as input.
