Consider the following recursive function: void recurse(int num) { if (num == 0) cout << “ Zero” << endl; else { cout << " " << num << " " << endl; recurse(num + 1) } } Is recurse (-2) a valid call? If a valid call, what is the output of the entire function execution? If not a valid call, explain why it is not a valid call.
