cool kata :)
don't get hung up on the standard function announcement form.

I agree with you, this code is wrong and not pass all test

but description not changed, or this inaccuracy write intentionally?

Thank you for comment, I do not known about this case.

ok, today all tests pass without error, thank for reaction.

1 language is python
2 i do not change input array in my programm
and my decision sometimes pass your tests, sometimes no.
maybe the problem in your implementation, why is the input set of [16, 17] your implementation gives a "tie"

Testing for [16, 17]
✘ It should work for random inputs too: 'tie' should equal 'odds win',

but [16, 17] -> [10000, 10001] -> 1 vs 2 odds win
