leetcode - 39. Combination Sum - Medium descrition Given a set of candidate numbers (C) (without duplicates) and a target number (T), find all unique combinations in C where the candidate numbers sums to T. The same repeated number may be chosen from…

[题目] Given a set of candidate numbers (candidates) (without duplicates) and a target number (target), find all unique combinations in candidates where the candidate numbers sums to target. The same repeated number may be chosen from candidates unlimi…

leetcode 39 先排序,然后dfs 注意先整全局变量可以减少空间利用 class Solution { vector<vector<int>>ret; vector<int>temp; vector<int> srt; public: vector<vector<int>> combinationSum(vector<int>& candidates, int target) { srt=candidate…

39. 组合总和 给定一个无重复元素的数组 candidates 和一个目标数 target ,找出 candidates 中所有可以使数字和为 target 的组合. candidates 中的数字可以无限制重复被选取. 说明: 所有数字(包括 target)都是正整数. 解集不能包含重复的组合. 示例 1: 输入: candidates = [2,3,6,7], target = 7, 所求解集为: [ [7], [2,2,3] ] 示例 2: 输入: candidates = [2,3,5…

Given a set of candidate numbers (C) (without duplicates) and a target number (T), find all unique combinations in C where the candidate numbers sums to T. The same repeated number may be chosen from C unlimited number of times. Note: All numbers (in…

题目链接: https://leetcode.com/problems/combination-sum/?tab=Description   Problem: 给定数组并且给定一个target,求出所有满足求和等于target的数字组合   遍历所有的数组中元素,然后对target进行更新,将该元素添加到tempList中,直到remain等于0时达到条件,可以将该tempList添加到list中   注意:每个元素可以使用多次,因此每次的遍历都要从上次的那个下标开始.   当target更新到…

39. Combination Sum 依旧与subsets问题相似,每次选择这个数是否参加到求和中 因为是可以重复的,所以每次递归还是在i上,如果不能重复,就可以变成i+1 class Solution { public: vector<vector<int>> combinationSum(vector<int>& candidates, int target) { vector<vector<int>> result; vector…
