You are given an*n*x*n*2D matrix representing an image. Rotate the image by 90 degrees (clockwise). **Note:** 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:** ~~~ Given input matrix = [ [1,2,3], [4,5,6], [7,8,9] ], rotate the input matrix in-place such that it becomes: [ [7,4,1], [8,5,2], [9,6,3] ] ~~~ **Example 2:** ~~~ Given input matrix = [ [ 5, 1, 9,11], [ 2, 4, 8,10], [13, 3, 6, 7], [15,14,12,16] ], rotate the input matrix in-place such that it becomes: [ [15,13, 2, 5], [14, 3, 4, 1], [12, 6, 8, 9], [16, 7,10,11] ] ~~~ 給定一個 n?×?n 的二維矩陣表示一個圖像。 將圖像順時針旋轉 90 度。 說明： 你必須在原地旋轉圖像，這意味著你需要直接修改輸入的二維矩陣。請不要使用另一個矩陣來旋轉圖像。 示例 1: ``` 給定 matrix = [ [1,2,3], [4,5,6], [7,8,9] ], 原地旋轉輸入矩陣，使其變為: [ [7,4,1], [8,5,2], [9,6,3] ] ``` 示例 2: ``` 給定 matrix = [ [ 5, 1, 9,11], [ 2, 4, 8,10], [13, 3, 6, 7], [15,14,12,16] ], ``` 原地旋轉輸入矩陣，使其變為: ``` [ [15,13, 2, 5], [14, 3, 4, 1], [12, 6, 8, 9], [16, 7,10,11] ] ```
