Given a matrix A, return the transpose of A. The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix. Example 1: Input: [[1,2,3],[4,5,6],[7,8,9]] Output: [[1,4,7],[2,5,8],[3,6,9]] Ex…

vector<vector<int>> transpose(vector<vector<int>>& A) { vector<vector<int>> V; int RowLen = A.size(); ].size(); ; j < ColLen; j++) { vector<int> v; ; i < RowLen; i++) { v.push_back(A[i][j]); } V.push_bac…

给定一个矩阵 A, 返回 A 的转置矩阵. 矩阵的转置是指将矩阵的主对角线翻转,交换矩阵的行索引与列索引. 示例 1: 输入:[[1,2,3],[4,5,6],[7,8,9]] 输出:[[1,4,7],[2,5,8],[3,6,9]] 示例 2: 输入:[[1,2,3],[4,5,6]] 输出:[[1,4],[2,5],[3,6]] 提示: 1 <= A.length <= 1000 1 <= A[0].length <= 1000 class Solution { public:…
