isSubsetSum(set, n, sum) = true, if sum == 0 The above solution may try all subsets of given set in worst case. Therefore time complexity of the above solution is exponential. The problem is in-factNP-Complete(There is no known polynomial time solution for this problem). We can solve...
dp/knapsack-problem/partition-equal-subset-sum Partition Equal Subset Sum 描述 Given anon-emptyarray nums containingonly 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] >...
I found this question in one of the interview challenge. I used the traditional sum of subsets logic to find all the possible sum for n elements and then tried to reconstruct non-overlapping subsets for a sum from the 2D DP array. I couldn't get all tc to pass. Is there any better ...
Given a non-empty array 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. Note: Each of the array element will not exceed 100. The array size will not exceed 200. ...

### 特例:子集和 DP 一种实现的伪代码如下: 维度比较大的情形,经常出现在一类叫做 **子集和 (SOS, Sum Over Subsets)** 的问题中。这是高维前缀和的特例。 问题描述如下。考虑大小为 $n$ 的集合的全体子集上面定义的函数 $f$,现在要求出其子集和函数 $g$,它满足 $$ \begin{array}{ll} \textbf{for...

Of course the naïve solution would be to generate all possible subsets and check their sum equals toKor not. But it would of course be computationally exponential to generate all possible subsets. To do so, the recursion would be:
Consider we have a set of n numbers, and we want to calculate the number of subsets in which the addition of all elements equal to x. Input first line has n, x and the next line contains n numbers of our set. In the output we have to calculate the number of subsets that have tot...
Given an array of integers nums and a positive integer k, find whether it’s possible to divide this array into k non-empty subsets whose sums are all equal. Example 1: Input: nums = [4, 3, 2, 3, 5, 2, 1], k = 4 Output: True ...
