Oh my God! Now I got it! Thank you so much! That description is so BADLY WRITTEN! It made no sense what I was supposed to do...

thank you. I could not have done it without your explanation

God bless you. I came here to see if someone explained the exercise in a more understandable way. I would have never in a million years understood it from the original description.

Same issue was raised above with its sourse found/explained. Closing this one.

read my message...

When solving using C#

C# and Java are ~32,000 times faster than JS? What?

just because their natural speed is different...? (JS should go higher, then)

wut!?? x/

The requirements between different languages are vastly different. In Python and JavaScript the input goes up to 2^16 while in Java and C# it can be as big as INT.MAX_VALUE.

35 is a perfect power
Expected: not null
But was: null

So confusing. Please, update the description.

The second point isn't true, because when you add three numbers, the number of operations is two.
