can anyone please tell me what to output if N=1 is given?

well, when I added to code:

if N=1 then begin writeln('0'); halt; end;

I've got WA on test 1.
With out such code I've got WA on test 7. So, test 1 - N=1.
But I'm not sure in correct solution:

my program outputs 4 3. But 4 can be got only like:
4 = 1 + 3;

So, then change is already included in paying. Smth strange, don't you think so?

I had WA1 with output 0 for N=1. With 4 3 I passed 1st test but failed with WA9 which is something like 12 or 81.

So, amount of tips must be POSITIVE.

why when n=1 answer 4 3?
i think it must be 3 2!!

2 can't be representeted of sum numbers(3^n, where every N can be used _1 time_).
