368. 最大整除子集 给出一个由无重复的正整数组成的集合,找出其中最大的整除子集,子集中任意一对 (Si,Sj) 都要满足:Si % Sj = 0 或 Sj % Si = 0. 如果有多个目标子集,返回其中任何一个均可. 示例 1: 输入: [1,2,3] 输出: [1,2] (当然, [1,3] 也正确) 示例 2: 输入: [1,2,4,8] 输出: [1,2,4,8] class Solution { public int max(int a,int b){ return a>b?a:b…

最大整除子集 给出一个由无重复的正整数组成的集合,找出其中最大的整除子集,子集中任意一对 (Si,Sj) 都要满足:Si % Sj = 0 或 Sj % Si = 0. 如果有多个目标子集,返回其中任何一个均可. 示例 1: 输入: [1,2,3] 输出: [1,2] (当然, [1,3] 也正确) 示例 2: 输入: [1,2,4,8] 输出: [1,2,4,8] 解题分析: 如果a%b==0,则a=mb,所以如果把数组排序后如果a%b==0,且b%c==0则a%c==0.这就为用动态规划实现…

Given a set of distinct integers, nums, return all possible subsets (the power set). Note: The solution set must not contain duplicate subsets. Example: Input: nums = [1,2,3] Output: [ [3], [1], [2], [1,2,3], [1,3], [2,3], [1,2], [] ] 题意: 给定一个含不同整数的集…

一.要求 二.知识点 1.回溯算法 回溯算法相当于穷举法加剪枝,回溯算法总是和深度优先同时出现的,采用深度优先策略回溯到根,且根节点的所有子树都被搜索一遍才结束,并剪掉不符合要求的结果 三.解题思路 (1)采用回溯算法 对于列表数据先对每层进行一次循环(每层代表数组的数量,从0到len(num)),对每层满足要求的数组添加的res结果中 class Solution(object): def subsets(self, nums): """ :type nums: List[…
