In an effort to better myself as an engineer and problem solver, I've integrated daily code problems into my routine.

Lucky for all of us wanting to get better at talking to computers, there's a service that delivers free coding problems straight to your inbox! Huzzah!

https://www.dailycodingproblem.com/

As I use lot's of different languages, I've decided to narrow myself down to using just three to get better at: C/C++, C#, and Python

*Note* - These are not the most elegant solutions to problems as I'm simply trying to come up with a solution as fast as I can. There may even be bugs. (Let me know if you find one and I'll be sure to give you a shout out!)
