+48. Rotate Image
+Difficulty: Medium
+https://leetcode.com/problems/rotate-image/
+
+──────────────────────────────────────────────────
+
+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, 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]]
+
+
+
+Constraints:
+
+        • n == matrix.length == matrix[i].length
+
+        • 1 <= n <= 20
+
+        • -1000 <= matrix[i][j] <= 1000

+class Solution:
+    def rotate(self, matrix: List[List[int]]) -> None:
+        n = len(matrix)
+        for r in range(n):
+            for c in range(r + 1, n):
+                matrix[r][c], matrix[c][r] = matrix[c][r], matrix[r][c]
+
+        for r in range(n):
+            matrix[r].reverse()
