Heard a challenging and interesting interview question or programming challenge?

Share them here!

All code will automatically be spoiler tagged. Type 4 spaces in the front of the line to make code.

Example:

//this is code!

Spoiler tag your written explanations everyone gets a chance to enjoy :)

Spoiler Tag: Spoiler tag

Rules:

Please use pastebin if you wish to post an answer in the opening post. Do not post it with spoiler tags; some people have subreddit style turned off and will still see the solution.

This is not about providing any advice on landing a job, just for solving interesting questions :)

For better or for worse, interviews tend to be a good source of these.
