Solution: Longest Consecutive Sequence

Explore solving the Longest Consecutive Sequence problem by implementing the Union Find pattern. Understand how to combine consecutive elements into connected components and efficiently find the longest consecutive run in an unsorted array. This lesson guides you through the algorithm and its complexity considerations.

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:
