Solution: 3Sum
Explore how to solve the 3Sum problem by applying the two pointers technique. Understand the process of sorting the array, using pointers to find unique triplets that sum to zero, and skipping duplicates. Learn about the time complexity and space considerations for an efficient solution.
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...
