It would be nice for the downvoter of the comment above to share some reasoning for their vote? My understanding was that downvotes were typically used to flag posts. Either way, anonymously downvoting is lame.

Yeah, people seem pretty happy to purge the methods entirely.

apparently not many people aliased the methods first, to allow possible usage after our "patches"

I have to learn numbers concept in ruby more. Such trick is good to push me to study better. lol for the up voted solution.

Excellent point, I added a new line saying that if there is only a single student, then they have the most money.

I originally left out the provided test, but then I realized it would be very difficult without it... Maybe I'll fork it and change how the checking works :)
