Really the worst kata :(

If array is [1.0, 1.0, 1.2, 1.3, 0.8, 0.9, 1.0] There will be a lot of wrong solutions.

Thanks a lot, now i understand :)

What's wrong with author's example? He claims, ideal traider got profit +50%. But it's not right.

1. I have $100, and can buy 120 stocks by 0.8.
2. I sell 120 stock by 1.2 = $150
3. I buy 166.66 stocks by 0.9
4. Sell it buy 1.0.
   So a got profit from 100 to $166.6. It's +66%, not +50%

I've never thought that 'Y' is not a vowel!!!!

Don't understand why this solutuin so liked and "clevered".It's doesn't work, because if min(total) == max(total) and len(students) > 1: - wrong condition.
cameron = 30, Phil = 30, Geoff = 15.
Cameron is winner, but right answer - all.

Too easy
