位运算直接搞

#include<iostream>

using namespace std;

int change(int x , int k)
{
    unsigned short y = x , z = x;
    unsigned short w = ((y << k) | (z >> (16 - k)));
    return w;
}

int main()
{
    unsigned short a , b;
    // cin >> a;
    // cout << change(a , 2);
    while(cin >> a >> b)
    {
        bool f = false;
        for(int i = 0;i <= 16;i ++)
        {
            if(change(a , i) == b || change(b , i) == a){f = true;puts("YES");break;}
        }
        if(!f) puts("NO");
    }
}
