Rotate Grid 90 Degrees Clockwise

You are given an n x n grid (matrix) containing integer elements. Your task is to rotate the grid by \(90^\circ\) clockwise.

Details:

• The input starts with an integer \(n\) which denotes the size of the grid.
• Following that, there are \(n\) lines with \(n\) space-separated integers on each line representing the grid.
• You need to output the rotated grid in the same format: \(n\) lines with \(n\) space-separated integers per line.

For example, rotating the grid below:

[ \begin{bmatrix} 1 & 2 & 3 \ 4 & 5 & 6 \ 7 & 8 & 9 \end{bmatrix} ]

results in:

[ \begin{bmatrix} 7 & 4 & 1 \ 8 & 5 & 2 \ 9 & 6 & 3 \end{bmatrix} ]

</p>

inputFormat

The input is read from standard input (stdin) and consists of:

1. An integer \(n\) on the first line, representing the dimensions of the grid.
2. \(n\) lines that follow, each containing \(n\) space-separated integers representing a row of the grid.

outputFormat

The rotated grid should be written to the standard output (stdout). The output must consist of \(n\) lines, each containing \(n\) space-separated integers corresponding to a row of the grid after a \(90^\circ\) clockwise rotation.
