Abstract: 3SUM is a very well known problem that has long been conjectured to be Ω(n 2). This has profound implications on the class of 3SUM-HARD problems. We explore the work of [6] that resulted in ...

The provided code is a correct and efficient solution to the classic "3Sum" problem, which aims to find all unique triplets in an integer array that sum to zero. The algorithm begins by sorting the ...

An additional test case that does not satisfy the question requirement should be present. Consider the array [-1, -1, 0, 1, 1, 2]. When you find the triplet [-1, 0, 1], you add it to the result. After ...
