CP-1.003 Java Tutorial - Bit Manipulation

Problem: Reverse Binary Numbers (https://open.kattis.com/problems/reversebinary) An exercise involving bit manipulation in Java. It can be done without bit manipulation (using String), but I think this problem is a great opportunity to show how bit manipulation works in Java. You need to understand how binary numbers work for this problem, so if this is new to you, please start by watching some videos on them. Here's a couple of good videos on binary number that I found on YouTube: - https://www.youtube.com/watch?v=LpuPe81bc2w - https://www.youtube.com/watch?v=1GSjbWt0c9M Please see https://www.youtube.com/watch?v=2vi1o0Fr0Uk for the start of this video series.
