you can use list slices

oh right, still confused regarding that way of writing code. Thanks :)

That return actually outside the loop, because he didnt add {}. The loop without curly bracket only take one action.

No, you have to return n numbers of the sequence, counting the ones of the signature too. So, the signature always has 3 elements, but if n is 0, you return an empty array/list, when n is 1, the first element of the signature, etc. I hope it is clearer now.

nice, I came up with the same code.:D except the return is outside the loop

yes, that's what the instructions said, but somehow the tests performed should also pass with signature given as [],[1] and [1,2] otherwise there will be failed tests.

You're confused there, signature always has 3 numbers:

Signature will always contain 3 numbers; n will always be a non-negative number; if n == 0, then return an empty array (except in C return NULL) and be ready for anything else which is not clearly specified ;)

n can be less than 3.

Any new programmers here? Hope you add me.

P.S. my current language is JavaScript
