A Way to Look at Tideman Lock Pairs

I've observed that there is a little bit of a disconnect in understanding what it is that needs to be done to properly implement the lock_pairs function for cs50 Tideman. The goal of this little write-up is simply an attempt at explaining what the problem actually is, and why a cycle imposes a problem.

First:
If you are unfamiliar with the actual problem, or have not read through the entire cs50 Tideman problem description. Then I think you should start there.
cs50 Tideman

Second:
This little write-up is only narrowing in on the idea of cycles, and a way to think about what a cycle is and determine if locking a pair in the pairs array would create that cycle. This does not talk about any other part of the Tideman problem.

Python environments in macOS

The latest version of macOS 10.13.3 has Python 2.7.10 installed by default, yet Python has been available on macOS and previously OS X for quite a while now.

Consult the Apple's Open Source Reference Library, and browse through the various releases of the OS to find out which Python version was included). But what if you have a project which requires Python 3 ?

The following instructions will guide you through the process of:

installing Python 3 using Homebrew
running multiple Python verions as sandboxed environments
