Daily Coding Problem

I signed up at dailycodingproblem.com and I’m posting my solutions in a Codepen.io collection.

Four questions in, three were not tough at all and one completely stumped me.

I bought this book to compensate:

Introduction to Algorithms, Second Edition

I got an old edition because it’s 20% the price and but it’s the same edition that would’ve been around when I was in college.
