User Submitted Solutions

Adding to the interesting 191 ways to echo hello world I’ve now added the ability to see user-submitted solutions to cmdchallenge.

There are some gems if you dig through them including maybe the longest regex I’ve ever seen for pulling an IP address out of a file:

(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)

Also scrolling down the page of solutions to the corrupted text problem is glorious.

The solutions are not updated regularly right now but would be easy enough to do in the future if people want to see more, let me know on twitter and also Update: Solutions are now generated every five minutes. Feel free to submit suggestions for new challenges on github.
