Oct 17, 2023 · Triplet Sum in Array (3sum) by generating all the triplets: A simple method is to generate all possible triplets and compare the sum of every triplet with the given value. The following code implements this simple method using three nested loops. Step-by-step approach: Given an array of length n and a sum s.
3Sum Leetcode Solution - Given an array of n integers, are there elements a, b, c in array such that a + b + c = 0? Find all unique triplet..
Given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] such that i != j, i != k, and j != k, and nums[i] + nums[j] + nums[k] == 0.
class Solution: def threeSum(self, nums: List[int]) -> List[List[int]]: nums.sort() ans = [] n = len(nums) i = 0 while i < n: if nums[i] > 0: break # Since arr[i] <= arr[l] <= arr[r], if arr[i] > 0 then sum=arr[i]+arr[l]+arr[r] > 0 l = i + 1 r = n - 1 while l < r: sum3 = nums[i] + nums[l] + nums[r] if sum3 == 0: ans.append([nums[i], nums[l ...
Aug 2, 2021 · In this Leetcode 3Sum problem solution we have given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] such that i != j, i != k, and j != k, and nums[i] + nums[j] + nums[k] == 0. Notice that the solution set must not contain duplicate triplets.
