Question 1 Problem Statement You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees clockwise. You must rotate the image in-place, which means you have to modify the input 2D matrix directly. Do NOT allocate another 2D matrix. Constraints n == matrix.length == matrix[i].length 1 <= n <= 20 -1000 <= matrix[i][j] <= 1000 Examples Example 1: Input: matrix = [[1,2,3],[4,5,6],[7,8,9]] Output: [[7,4,1],[8,5,2],[9,6,3]] Explanation 1: Transpose the matrix (swap matrix[i][j] with matrix[j][i]) ...
