Problem A：

#include <cstdio>
#include <iostream>
using namespace std;

#define F(i,a,b) for(int i=a;i<b;i++)


int main(){
    int n,x;
    scanf("%d%d",&n,&x);
    n %= 6;
    while(n--){
        if(n & 1){
            if(x!=0) x=3-x;
        }else{
            if(x!=2) x=1-x;
        }
    }
    cout<<x<<endl;
    return 0;
}
