Solution: Rotate Image

Understand how to perform an in-place 90 degree clockwise rotation on an n x n matrix. Learn to group cells and apply swaps efficiently, mastering matrix traversal techniques for image transformations and optimizing time and space complexity.

We'll cover the following...

Statement

Given an n×nn \times n matrix, rotate the matrix 90 degrees clockwise. The performed rotation should be in place, i.e., the given matrix is modified directly without allocating another matrix.

Note: The function should only return the modified input matrix.

Constraints:

  • matrix.length == matrix[i].length
