The challenge

Given the matrix [[1,2,3],[4,5,6],[7,8,9]], rotate it 90 degrees clockwise and print each row of the result on its own line, space-separated.

Output

🧠 Need a hint? (Python)

For an n x n matrix, rotated[j][n-1-i] = mat[i][j] for every i, j -- build a new n x n grid and fill it with that mapping.
