K-Sum – A generalized solution

In this blog post, we will attempt to address the 4-Sum problem from Leet code using the generic approach of K-Sum. Let us state the official definition of the problem. Given an array nums of n integers, return an array of all the unique quadruplets [nums[a], nums[b], nums[c], nums[d]] such that: 0 <= a, b, … Continue reading K-Sum – A generalized solution
