This "100 characther" rule need to be reviewd.

First: I put my code in chrome and it gives length = 76. But here, the count is 97!

I'm not a fan of oneline codes, otherwise, i like this kata. (Just need to improove this characther rule, maybe rising to 150).

The official test is ok.

Try print the bill value and you'll see your error.

I've searched here and i did not found a similar kata.
