Given a positive integer n, generate a square matrix filled with elements from 1 to n2 in spiral order. Example: Input: 3 Output: [ [ 1, 2, 3 ], [ 8, 9, 4 ], [ 7, 6, 5 ] ] class Solution { public: vector<vector<int>> generateMatrix(int n) { ve…

54题是把二维数组安卓螺旋的顺序进行打印,59题是把1到n平方的数字按照螺旋的顺序进行放置 54. Spiral Matrix start表示的是每次一圈的开始,每次开始其实就是从(0,0).(1,1)这种开始的. 用endx.endy来表示每次转圈的x.y方向的终止位置,方便后面进行边界条件设置. 注意:后面start < endx && start < endy.start < endy && start < endx-1都必须同时满足x.y的条…
