Solution: Longest Consecutive Sequence

Understand how to use the Union Find algorithm to identify the longest consecutive sequence in an unsorted array. This lesson covers initializing the structure, combining consecutive elements, and tracking the largest connected component efficiently, helping you apply this pattern to similar coding challenges.

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:
