You are given an array Arr consisting of N integers, you need to find all the distinct triplets present in the array which ad Nov 24, 2022 路 Practice three sum coding problem. Aug 1, 2023 路 STEP 1: We have ‘nums’ vector as input and returns a vector of vectors representing the triplets that sum up to zero. The 3Sum (LeetCode 15) problem is a classic algorithm challenge often encountered in software engineering interviews, particularly at companies like Google, Facebook, and Amazon. io/ - A better way to prepare for Coding Interviews 馃‍馃捈 LinkedIn: / navdeep-singh-3aaa14161 more 3 Sum | Brute - Better - Optimal with Codes take U forward 970K subscribers Subscribed Aug 1, 2025 路 Given an array arr [] of n integers and an integer target, find the sum of triplets such that the sum is closest to target. Make use of appropriate data structures & algorithms to optimize your solution for time & space complexity & This will have all the solutions to the competitive programming course's problems by Coding ninjas. Jul 23, 2025 路 We have discussed one more approach, that works for sorted arrays, in the post 3 Sum - Count Triplets With Given Sum In Sorted Array. So, the answer will always exist. If we fix one of the numbers say x, we are left with the two-sum problem at hand! To efficiently find the j and k pairs, we run the two pointer approach on the elements to the right of index i as the array is sorted. 馃殌 https://neetcode. Nov 20, 2020 路 Practice 3sum coding problem.
