Daily programming challenges: Why I do them

Hello,

This is just a rant about my programming challenges.

First of all: I'm a 13-yo boy programming about the half of the day, my project in the moment is building a compiler (I will post something about that later).

Building a compiler needs lots of training, which is why I want to help others get there by giving them challenges. 

AND here comes the breaking point: many of my challenges aren't that easy (wich implies time-consuming). 

As I have to finish my compiler in aprox. 3 Weeks, I can't do the challenges for myself, but I really motivate you, if you want to share your solution with me, post it on github and then send me the link. 

Just don't answer directly in the comments ;-)
