At least one where you have to reduce the given fractions first. :)

Yes. My not too interesting idea was to make the calculation a bit more complex if the array did not add up to a round number.

Thanks for the feedback guys

Your bookkeeping eludes me.

If we rake in [1], wouldn't Dr. Evil get 1 billion, and I .999 trillion?

NEVER, EVER, comparing floating directly, or you are make a guess what calculation the author is using kata.

const me = sum - evilTr - (evilTr - sum/1000);

this, from the reference solution, is mathematically identical to

sum - evilTr - evilTr + sum/1000
sum - 2 * evilTr + sum/1000
1.001 * sum - evilTr - evilTr
...

Substitute your solution with thses and attmpt then find out how lucky are you able to pass the test.
