Given two sorted arrays of numbers, return an array containing all values that appear in both arrays. The numbers in the resulting array (the "intersection") may be returned in any order, they needn't be sorted.
You can assume that each array has only unique values (no duplicates within the array).

OOP Design is a good exercise on how to split up our system into different objects/classes. The main difficulty with problems like these are that they are open-ended and force you to think abstractly and creatively. One of the other main goals of this exercise is to be able to draw out diagrams to help with communicating abstract ideas before they are implemented in code. These problems are language agnostic.
PROMPT: Using object oriented programming principles, class diagrams and activity diagrams, design an ATM.
We are being explicit here, however, you might not get this luxury from an interviewer as they might just ask, "Using object oriented design, design an ATM".

Currying is the process by which a function of N arguments is implemented as N single-argument functions such that first of them takes in the first argument and returns a function which takes in the 2nd argument and so on, until the Nth single-argument function finally returns the value of the multi-argument function being implemented.

You're an industrious programmer that lives off the grid. The local well that you use to fetch water has gone dry, so you've decided to collect rain water to filter; however, your collection device isn't flat.
Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water your collection device is able to trap after raining.
