Cheat, "Do not use built in functions."

Fu#!ng Genius

cheat =_=

Very clever... -_-

"Do not use built in functions."

You shouldn't be upvoting this.

"NOTE: There will also be lists tested of lengths upwards of 10,000,000 elements. Be sure your code doesn't time out."

You only get to the next rank if the progress for you current rank reaches 100.
Therefore, solving a rank -8 kata on a rank -7 account will give you 1 point, not 1 rank, thus your rank will remain -8 and you will have progress = 1.
