48 - Rotate Image\. Medium You are given an `n x n` 2D `matrix` representing an image, rotate the image by **90** degrees (clockwise). You have to rotate the image [**in-place** ](https://en.wikipedia.org/wiki/In-place_algorithm), which means you have to modify the input 2D matrix directly. **DO NOT** allocate another 2D matrix and do the rotation. **Example 1:**  **Input:** matrix = \[\[1,2,3],[4,5,6],[7,8,9]] **Output:** [[7,4,1],[8,5,2],[9,6,3]] **Example 2:**  **Input:** matrix = \[\[5,1,9,11],[2,4,8,10],[13,3,6,7],[15,14,12,16]] **Output:** [[15,13,2,5],[14,3,4,1],[12,6,8,9],[16,7,10,11]] **Example 3:** **Input:** matrix = \[\[1]] **Output:** [[1]] **Example 4:** **Input:** matrix = \[\[1,2],[3,4]] **Output:** [[3,1],[4,2]] **Constraints:** * `matrix.length == n` * `matrix[i].length == n` * `1 <= n <= 20` * `-1000 <= matrix[i][j] <= 1000`
