I am not really sure what my code is doing wrong, but it currently returns an empty list for this list [-1, 0, 1, 2, -1, -4], so it is not recognizing any triplets that sum to 0. The pattern uses two pointers that either converge from opposite ends or Day 19 of my LeetCode journey 🚀 Today I solved the 3Sum problem using Java, and it was a great learning experience.

Another step forward 🚀 Consistent effort, steady growth — learning every day. Let's see code, 15. It's better we should go for kSum solution. Jul 26, 2022 · In the scenario I present to you, my solution is supposed to represent O (n^2 * log n), and the "pointers" solution, which I assume is the fastest way to resolve the "3SUM" problem, represents O (n^2 * 1); leaving the question of is O (1) faster than O (log n), exampling it with my code. 3Sum problem of Leetcode. 4Sum and 3Sum are very similar; the difference is that we are looking for unique quadruplets instead of triplets. This problem really helped me understand the importance of sorting and the Hi Connections! 👋 Solving LeetCode problems everyday & currently on a 246 Days Streak🔥👨💻 🧠 Problem No: 15 – 3Sum ⭐ Difficulty: Medium 📄 Problem Statement Given an integer In this post, we are going to solve the 15. 3Sum. But you can easily improve on that bound by first indexing the numbers and then computing all the sums of pairs, storing them in a hash table and then lookup if the negative of the sums exists and test if its components have not already been used in Aug 12, 2016 · Leetcode #15: 3sum -- avoiding duplicate Asked 9 years, 6 months ago Modified 9 years, 6 months ago Viewed 2k times Aug 22, 2020 · This problem is a follow-up of 3Sum. My aim to provide more than just solutions. Following a similar logic, we can implement 5Sum by wrapping 4Sum in another loop. To see which sums of three are 0 all sums are computed and there are N * (N-1) * (N-2) / 4 different sums. However, I disagree with the other answers concerning space complexity and believe it is quadratic as there can be quadratically many distinct triples summing to 0. Following code will work for 2Sum, 3Sum, 4Sum and so on. #100DaysOfLearning #LeetCode #DSA #TwoPointers #Java #ProblemSolving #CodingJourney #LearningInPublic #Consistency 15.
