根据issac3 用Java总结了backtracking template, 我用他的方法改成了Python. 以下为template. 可以用来解决的问题有: Leetcode 78. Subsets , Leetcode 90. Subsets II, Leetcode 4
Given a non-empty array nums containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal. Example 1: Input: nums = [1,5,11,5] Output: true Explanation: The array can be partitioned as [1, 5, 5]...
Permutations 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...
Partition a set into k subset with equal sum: Here, we are going to learn to make partitions for k subsets each of them having equal sum using backtracking.
Enumerate all the subsets of the given array to see how many of them match the condition when you write backtracking procedure using recursion, please be careful of which condition do you use to terminate the loop, in this code snippet, there two conditions, ...

Sum of subset differences in C - In this problem, we are given a set S of n number. Our task is to create a program to find the sum of subset difference which is the difference of last and first elements of subset.The formula is,sumSubsetDifference = Σ
