Write a function that takes an array of floats (or doubles) as a parameter and returns a longest subsequence of floats where all elements have differences not more than 1 between each other. For example input: [4.2, 5.3, 4.6, 9.8, 1.5, 5.2, 4.7] output: [4.2, 4.6, 5.2, 4.7], -> if you find the difference between any pair of elements here, it would be less or equal then one.
