Answer 1

#include "stdafx.h"
#include <iostream>
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
int x, y, r;
r = 0;
cin >> x;
cin >> y;
for(int i = 15; i >= 0; i--){
int t = 1;
t = t << i;
r = r << 1;
t = t & y;
t = t >> i;
r += t;
r = r << 1;
t = 1;
t = t << i;
t = t & x;
t = t >> i;
r += t;
}
return 0;
}
