Solution: 3Sum
Explore the two-pointer approach to solve the 3Sum problem in JavaScript. Understand how sorting the array and using two pointers helps find unique triplets summing to zero while avoiding duplicates. Gain skills to optimize time complexity and manage space efficiently.
We'll cover the following...
Statement
Given an integer array nums, find all unique triplets [nums[i], nums[j], nums[k]] where i, j, and k are distinct indices, such that the three elements sum to zero.
The result must not contain any duplicate triplets. The order of the output and the order of elements within each triplet does not matter.
Note: The solution set must only include unique triplets. Two triplets are considered duplicates if they contain the same elements regardless of ordering.
Constraints:
nums.length...
