Category: Algorithms December 23, 2012. Problem: Given an array S of n integers, are there elements a, b, c in S such that a + b + c = 0? Find all unique triplets in the array which gives the sum of zero. Note: Elements in a triplet (a,b,c) must be in non-descending order. (ie, a ≤ b ≤ c) The solution set must not contain ...Simple Approach: The naive approach is to explore all the subsets of size 3 and keep a track of the difference between X and the sum of this subset. Then return the subset whose difference between its sum and X is minimum. Algorithm: Create three nested loops with counter i, j and k respectively.3. Create two pointers: left, pointing to element right after x. right, pointing to last element. 4. While left pointer is less then right compare their sum to -x: sum < -x, shift the left pointer to the right. sum > -x, shift the right pointer to the left. sum = -x, store triplet a, b, c it in the result variable, and shift the left pointer to ...Summary for LeetCode 2Sum, 3Sum, 4Sum, K Sum Overview I summarize various solutions (sort, hash, etc) for the leetcode 2Sum, 3Sum, 4Sum problems as well as how to optimize and some important r.
