Problem: Longest Consecutive Sequence
Explore how to identify the longest consecutive sequence in an unsorted integer array by using a hash set for efficient lookups. Understand how to optimize for O(n) time complexity by starting sequences only at their smallest element and iterating through the array with minimal overhead.
