Problem 1

 -- Just to be clear, the input values for problem are integers. They may be negative (or 0). All 4 being 0 indicates end of input.

Problem 2

Problem 3

 -- > Are you sure that your output for number 3 is correct? When doing the
-- > third test case by hand we get 17.

I got 22 by hand (and by solution).

--> Are a, n and p positive, or just non-negative? That is, could either be 0?
They are all positive. 0s only appear in the last input line to terminate input.

-- > Does the judge's compiler support the function itoa?

Nope.
It's not a standard thing and can't be done portably because of varying implementations. You probably want something like `sprintf' or use the `stringstream' class.
