DIY: Monotonic Array
Understand how to identify monotonic arrays by implementing a function that checks if an array is entirely non-increasing or non-decreasing. This lesson helps you solve common array problems often seen in coding interviews by applying clear logic to real-world scenarios.

Problem statement
An array is monotonic if it is either monotone increasing or monotone decreasing.
An array, arr, is monotone increasing if arr[i] <= arr[i + 1] for every element at each index i. ...
