Cool!

Awesome!

Just when I think I did good, someone else does it in one line TT

Approved.

Thanks!

Lua translation!

In python I wrote up a solution however very occasionally it would fail some random tests for example:

a = 40 b = 47 c = 4 -1.18 should equal -1.17

I think there is something wrong in the reference solution when testing the random cases because

-47/40 = -1.175 and if you round this to 2dp it will be -1.18

Thanks! I see it is already approved, will mark as resolved.
