Problem: Longest Consecutive Sequence
Explore how to determine the longest consecutive sequence in an unsorted integer array by leveraging hash sets for O(1) lookups. Understand key optimizations that ensure linear time complexity, and implement a solution in JavaScript that effectively handles duplicate entries and scales to large input sizes.
