Solution: 3Sum
Explore how to solve the 3Sum problem by implementing the two-pointer technique on a sorted array. Understand how to avoid duplicates and manage pointers for efficient searching. This lesson helps you develop a pattern-based approach to identify all unique triplets that sum to zero, enhancing your interview preparation skills.
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...
