这道题比较简单,只要求出牛牛吃的蛋挞个数和b个人中每个人吃的蛋挞数量,比较一下 即可

#include <iostream>
using namespace std;
int main()
{
    long long a,b,i,x,y;
    cin >> a >> b;
    for(i=1;b*i<=a;i++);
    x=a-((i-1)*b);//牛牛吃的
    y=i-1;//b个人中每个人吃的
    if(x>y)
        cout << "niuniu eats more than others" << endl;
    else if(x<y)
        cout << "niuniu eats less than others" << endl;
    else
        cout << "same" << endl;
    
}
import java.util.* ;

public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in) ;
        long a = sc.nextLong() ;
        long b = sc.nextLong() ;
        long c = a / b ; //每人分多少个蛋挞
        long m = a - b * c ;//牛子吃的蛋挞
        if(c > m)
            System.out.println("niuniu eats less than others") ;
        else if(c < m)
            System.out.println("niuniu eats more than others") ;
        else
            System.out.println("same") ;
    }
}
}
