A Function NOBODY Told Me About

Okay, now I'm angry.

The puzzle NEVER - ahem. The puzzle takes an input as a list. I'm sure I could find the median easily enough, if the list were sorted. It's a small thing, but I'm SO upset. I used up all my hints because I wasn't ready to sort by list iteration or anything like that. No, that's deserving of its own puzzle.

What enrages me most is the hint after "I am stuck. I need a small hint." "Don't forget to sort the array." Well EXCUSE ME, smarty pants, I KNO-ahem.

I just wish I was clued in to the function array.sort(), and think that it should be mentioned perhaps in the very first clue.
