How to write a recursive function in reverse?

[vaultDweller]

So I'm writing an assignment that prints out these number that change if the user entered number is a certain value (see code). This is done with a recursive function. Now I need to write the same recursive function and print the same output, only in reverse, and I'm not sure how to do that. So my question is, how can I write the same recursive function, but change it so that is prints in reverse? Thanks! :)

#include <iostream>
using namespace std;

void reverseOJP() {

	// ?

}

int lengthOJP (int D, int count) {

	cout << endl << "The length of the OJP for " << D << " is " << count << endl;

	return 0;
}

void OJP(int D, int count, int refD) {

	if (D == 1) { // Base case

		count++; // counter
		cout << endl;

		reverseOJP(); // call and print reverse OJP
		lengthOJP(refD, count); // Once reverse is printed print length

	} else if ((D % 2) != 0) { // odd numbers

		D = ((D * 3) + 1); // if D is odd
		count++; 
		cout << D << " ";

		OJP(D, count, refD); // Recursive Call

	} else { // even

		D /= 2;
		count++;
		cout << D << " ";

		OJP(D, count, refD);
	}
}

int main() {
	int D, refD, count = 0; // variables

	// user prompt and input
	cout << "Enter a positive integer: " << endl;
	cin >> D;

	// OJP output
	cout << "The OJP for " << D << endl;
	cout << D << " ";

	refD = D; // D reference for output purposes
	OJP(D, count, refD); // OJP call

	return 0;
}
