Subsets是「组合」,Permutations是排列。 那么这题也容易想到,跟subsets相比,把进入下一层dfs的i+1去掉就好了(同时要加上terminator哦)。但是这样一来对于[1,2,3]这样的nums,第一个解会变成[1,1,1]呀。怎么办,增加一个数组来保存是否使用过(模拟HashMap),有点像图的遍历了。或者直接利用ArrayList的contains函...

Then we will choose any of the value from starting and start our backtracking algorithm according to that and find the subsets with equal sum,{85,21,23,70,85} {28,59,31,93,73} {29,51,25,97,82} C++ Implementation#include <bits/stdc++.h> using namespace std; bool is_partiable(int...
Given a set of non negative integers and a target value, find if there exists a subset in the given set whose sum is target. Solution 1. Enumerate all possible subsets and check if their sum is the target The runtime of this solution is O(2^n). This enumeration algorithm is similar ...
