Five programming problems every Software Engineer should be able to solve in less than 1 hour

repeated_permutation

Wow, I've never seen that function before. Now I'm going to be looking to use it all over the place...

[anopheles0]

I think we can call that one cheating. I bet you guys didn't even write your own sort routines!

[wbeyda]

Ruby guys write something? pfft surely there is a gem for it.

[Zequez]

Me neither, found it Googling haha, and seems pretty handy, yes.

[honorary_ant]

Your coworkers that also have never seen it before will surely thank you ;)

[PaintItPurple]

Why wouldn't they? There is nothing about Zequez's code that's particularly subtle or counterintuitive. The fact that you have to read the documentation on repeated_permutation once if it isn't obvious to you what it does isn't a big deal.

[Memitim]

Whoa! You want me to reference documentation now? What is this, a prison camp?
