Task Description

3Sum Problem (LeetCode Style)

Problem Statement

Given an integer array nums, return all the unique triplets [nums[i], nums[j], nums[k]] such that:

i != j, i != k, and j != k
nums[i] + nums[j] + nums[k] == 0

Example

Input: nums = [-1, 0, 1, 2, -1, -4]

Output: [[-1, -1, 2], [-1, 0, 1]]

The solution set must not contain duplicate triplets.

Constraints

3 <= nums.length <= 3000
-10^5 <= nums[i] <= 10^5

Required Function (JavaScript)

/**
 * @param {number[]} nums
 * @return {number[][]}
 */
function threeSum(nums) {
    // Your code here - O(n^2) time complexity expected
}

Solution Template

/**
 * @param {number[]} nums
 * @return {number[][]}
 */
function threeSum(nums) {
    // Implement the 3Sum algorithm here
    // Expected: O(n^2) time, return all unique triplets summing to zero
    return [];
}
