Solution: Longest Consecutive Sequence

Explore how to solve the longest consecutive sequence problem in an unsorted array using the Union Find pattern. Learn to initialize and merge connected components, analyze consecutive elements, and determine the maximal sequence length efficiently with O(n) time complexity.

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:
