## Description
Given an unsorted array of integers, find the length of the longest consecutive elements sequence.
Your algorithm should run in O(n) complexity.
Example:
Input: [100, 4, 200, 1, 3, 2]
Output: 4
Explanation: The longest consecutive elements sequence is [1, 2, 3, 4]. Therefore its length is 4.

Is the period of f(x) = 2cos(3x - ð) 2ð/3?
• Pre-Calculus -
ð = pi
• Pre-Calculus -
one period is from x = 0 to x = 2 pi/3
so that the argument of the trig function changes by 2 pi
so the answer is 2 pi/3
