Question 867. Transpose Matrix Solution 题目大意:矩阵的转置 思路:定义一个转置后的二维数组,遍历原数组,在赋值时行号列号互换即可 Java实现: public int[][] transpose(int[][] A) { int[][] B = new int[A[0].length][A.length]; for (int i = 0; i < A.length; i++) { for (int j = 0; j < A[0].length; j++…
Given an integer n, generate a square matrix filled with elements from 1 to n2 in spiral order. For example, Given n = 3, You should return the following matrix: [ [ 1, 2, 3 ], [ 8, 9, 4 ], [ 7, 6, 5 ]] 解题思路: 参考Java for LeetCode 054 Spiral Matrix,修改下…
