## Set Theory for Programmers

Set Theory If you’ve spent time on HackerRank or LeetCode, you might have noticed most of the optimal solutions use Set Theory. By reading this article, you will gain a deeper knowledge into set theory and how to use it to create optimal algorithms. Set Theory was invented (or found, depending on how you view maths) by George Cantor. It revolves around the idea of sets, as in collections of objects....
