In this lesson, we are going to be solving the “Two-Sum Problem”. Let’s begin by defining the problem. Given an array of integers, return True or False if the array has two numbers that add up to a specific target. You may assume that each input would have exactly one solution.
We investigate three different approaches to solving this problem.
