Question

problemset 3 problem 1 recursive
i dont understand how do to this problem because it seems paradoxical, you must define a count at 0, but when you go back to the base case, the program resets the count. could someone explain an alternative way for this problem or a way around this?

Answer 1

For the first problem, you can pass a hidden argument to the recursive function and it will count okay, check: http://codepad.org/aTGMRw3n
There is a minor catch in writing the code this way, see if you can solve it.

Are you having other problems understanding the problem set? :-)
