I think we all can agree on this: Two-Sum Algorithm is sort of a classic data structure challenge. In my blog, I’d like to share two approaches to solving it. The first one is a so-called “brute force” method, and the second one represents a more elegant solution

So, our problem is: Given an array of numbers and a target number, find the sum of two numbers from the array that is equal to the target number. May not sum the same index twice. Return these numbers.
