[Leetcode] Spiral Matrix | 把一个2D matrix用螺旋方式打印 Java 版本代码如下: publicint[][] generateMatrix(intn) {int[][] res =newint[n][n];intvalue = 1;intleft = 0, right = n-1, top = 0, bottom = n-1;while(top < bottom && left <right) {//corresponding to the red part...
res.add(matrix[i][i+j]); for(int j = 0; j < m - 1 - i * 2; j++) res.add(matrix[i+j][n-i-1]); for(int j = 0; j < n - 1 - i * 2; j++) res.add(matrix[m-i-1][n-i-1-j]); for(int j = 0; j < m - 1 - i * 2; j++) res.add(matrix[m-i-...
Given a matrix of m x n elements (m rows, n columns), return all elements of the matrix in spiral order. For example, Given the following matrix: [ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 7, 8, 9 ] ] You should return[1,2,3,6,9,8,7,4,5]. 顺序添加法 复杂度 时间O(NM) ...
LeetCode Top Interview Questions 59. Spiral Matrix II (Java版; Medium) 题目描述 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 ] ] 1. 2. 3. 4....
【LeetCode-面试算法经典-Java实现】【全部题目文件夹索引】 原题 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 ], ...
matrix[x][endy] = num++; } // 如果行或列遍历完,则退出循环 if (startx == endx || starty == endy) { break; } // 下边的行,从右向左 for (int y = endy - 1; y >= starty; y--) { matrix[endx][y] = num++;
Spiral Matrix 题目大意 将一个矩阵中的内容螺旋输出。 注意点: 矩阵不一定是正方形 例子: 输入: matrix = [ [ 1, 2, 3], [4, 5, 6], [7, 8, 9] ] 输出: [1, 2, 3, 6, 9, 8, 7, 4, 5] 解题思路 看代码就可以理解 注意: ...
在http://rosettacode.org/wiki/Spiral_matrix中列举了所有编程语言的螺旋阵的解决算法. 那天自己用matlab尝试写算法,并没有查过资料,凭着自己的思路写了两段程序. 第一段: function [b]=SpiralMatrix(n) c=[0 n-1:-1:1;n-1 n-1:-1:1];i=1;j=1;d=0;t=1;y=1;b(1,1)=1; ...
