主要求出當前是不是奇異局勢就好啦~

要用到黃金分割~

程式碼：

#include <cstdio>
#include <cstring>
#include <iostream>
#include <algorithm>
#include <cmath>
const int MAXN=10000;
using namespace std;
int main (void)
{
    long long a,b;
    double shu=(1 + sqrt(5.0))/2.0;
    while(~scanf("%lld %lld",&a,&b))
    {
        if
 
 (a > b)
            swap(a, b);
        long long k = b - a;
        if (a == (long long)(k * shu))
        {
            printf("0\n");
            continue;
        }
        else
        {
            printf("1\n");
            continue;
        }
    }
    return 0;
}
