Solution: Longest Consecutive Sequence

Explore how to solve the longest consecutive sequence problem by applying Union Find techniques. Understand how to merge consecutive elements into connected components and identify the largest sequence efficiently. This lesson covers implementation details, complexity considerations, and how to leverage data structures to optimize your approach.

We'll cover the following...

Statement

Given an unsorted array, nums, your task is to return the length of the longest consecutive sequence of elements. The consecutive sequence of elements is such that there are no missing elements in the sequence. The consecutive elements can be present anywhere in the input array.

Note: Two elements, xx and yy, are called consecutive if the difference between them is equal to 11.

Constraints:
