Find K-Sum Subsets

Explore techniques to identify all subsets of an array that sum to a given target k. This lesson helps you understand the problem constraints, think through logical steps, and implement efficient C# solutions for the k-sum subset problem. You'll gain skills in subset handling and algorithm optimization relevant to coding interviews.

Statement

Given an array of nn distinct positive integers, find all possible subsets of these integers such that the sum of the elements in each subset equals a given target value k.

Return a 2D array, where each inner array represents a subset whose sum equals k.

Constraints:
