Well MattyT has so elegantly solved the two problems (see his comment on the previous post) that this post is now a bit redundant. But having the solutions stashed away in the comments avoids people accidentally seeing them before reading the questions, so that's quite neat.
Nice work Matty, just let me know any time you want to form a Page-and-Brin-style techie partnership and change the world (sorry, I've been reading The Google Story and it's very inspiring!)
If you've been unable to nut out a solution to Question 4, don't worry. When we worked though my answers to the questions, my interviewers admitted than none of them (and there were four of them) were able to work out how to do it - given an unlimited amount of time!
Oh, and on the subject of comments, please note that I have enabled "anonymous commenting" so any of you guys can comment on our posts without having to have Blogger/Google accounts etc... Give it a go, it's always great to hear from you.
