Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space. Example output for userNum = 20:

20 10 5 2 1
existing code:

#include
using namespace std;

int main() {
int userNum = 0;

userNum = 20;

/*Your solution goes here*/

cout << endl;

return 0;
}
