Day 696 | Leetcode 3291| Find the Maximum Length of Valid Subsequence I

Video Summary:
We are given an array nums. We need to return the length of the longest valid subsequence.

Valid subsequence is defined as when the parity of sum of adjacent pairs is equal.
(nums[0[ + nums[1]) % 2 == (nums[1] + nums[2]) % 2
