Mind-bending Puzzles

Stumbled upon this site, with programming/math problems. The first few are fairly easy, but then the difficulty level grows.

An interesting observation I've made from watching other people's solutions is that the Ruby solution is almost always the smallest one.

|edit| Ok, I retract that statement. The smallest programs seem to be written in J. |edit|

The first one is very easy. Use n%3 == 0 to determine whether a number is a multiple of three or not.

|edit| Just because the smallest solutions were made in Ruby that doesn't mean that they were the easiest to come up with. |edit|

|edit| I'm particularly proud of my solution for level 3 in C#:

Later I looked it up and they had the EXACT program I was having problems with - turns out I had a typo in my answer
