DIY: Monotonic Array
Understand how to identify monotonic arrays by implementing a function that returns true if an array is either entirely non-increasing or non-decreasing. This lesson helps you apply key problem-solving skills for coding interviews and familiarizes you with array-based challenges.

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. ...
