DSA Problem 008: Longest Consecutive Sequence

#dsa #javascript Solution: https://github.com/therajatg/DSA/blob/main/008-longest-consecutive-sequence.js Given an array of integers, return the length of the longest consecutive sequence of elements that can be formed. A consecutive sequence is a sequence of elements in which each element is exactly 1 greater than the previous element. The elements do not have to be consecutive in the original array. You must write an algorithm that runs in O(n) time. // Input: nums = [20,2,4,10,3,4,5] // Output: 4
