leetcode讲解--867. Transpose Matrix

题目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]]Example 2:Input: [[1,2,3],[4,5,6]]Output: [[1,4],[2,5],[3,6]]Note:1 <= A.length <= 10001 <= A[0].length <= 1000题目地址讲解转置一个矩阵，简单。Java代码class Solution { public int[][] transpose(int[][] A) { int[][] result = new int[A[0].length][A.length]; for(int i=0;i<A.length;i++){ for(int j=0;j<A[i].length;j++){ result[j][i] = A[i][j]; } } return result; }}
