Nov 10, 2020 · 3 Sum. Problem Statement. Given an array nums of n integers, are there elements a, b, c in nums such that a + b + c = 0? Find all unique triplets in the array which gives the sum of zero. Notice that the solution set must not contain duplicate triplets. Constraints: 0 ≤ nums.length ≤ 3000. -10 5 ≤ nums[i] ≤ 10 5. Examples. Example 1:
public List<List<Integer>> threeSum(int[] arr) { Arrays.sort(arr); int n = arr.length; List<List<Integer>> ans = new ArrayList<> (); for (int i = 0; i < n; i++) { if (arr[i] > 0) break; // Since arr [i] <= arr [l] <= arr [r], if a [i] > 0 then sum=arr [i]+arr [l]+arr [r] > 0.
