Solution: Longest Consecutive Sequence

Explore how to find the longest consecutive sequence in an unsorted array by applying the union find pattern. Learn to combine consecutive numbers into connected components, track their sizes, and determine the longest sequence with a linear time complexity 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:
