class Solution { public: vector<int> largestDivisibleSubset(vector<int>& nums) { vector<int> dp(nums.size(),0); //dp[i] 代表 nums[i]在nums里面能够整除的数字个数 1,2,3, 里面 dp[2]代表index=2的数 3 能够整数的数有1个; vector<int> idx(nums.size(),0); //记录每个索引…

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:集合: [1,2,3]结果: [1,2] (当然, [1,3] 也正确)示例 2:集合: [1,2,4,8]结果: [1,2,4,8]详见:https://leetcode.com/problems/largest-divisible-subset/description/ C++:…

Very nice DP problem. The key fact of a mutual-divisible subset: if a new number n, is divisible with the largest number m within a mutual-divisible set s, s U {n} is also a mutal-divisible subset. class Solution { public: vector<int> largestDivisib…
