Description
An integer array is monotonic if it never changes direction — it either stays non-decreasing throughout or non-increasing throughout.
Given an integer array nums, return true if nums is monotonic, or false otherwise.
Example 1:
Input: nums = [1,2,2,3]
Output: true
Example 2:
Input: nums = [6,5,4,4]
Output: true
Example 3:
Input: nums = [1,3,2]
Output: false
