分析:分析当整除(a+b)的时候肯定是后者胜利,假设余数不等于0的时候,假设余数大于b肯定是前者胜利。否则后者胜利。

代码:

import java.math.*;
import java.util.Scanner;

public class Main{
	public static void main(String[] args){
		Scanner cin = new Scanner(System.in);
		BigInteger n, a, b;
		while(cin.hasNext()){
			n = cin.nextBigInteger();
			a = cin.nextBigInteger();
			b = cin.nextBigInteger();
			a = a.add(b);
			n = n.mod(a);
			//System.out.println(n);
			if(n.compareTo(BigInteger.ZERO) == 0) System.out.println("Yougth");
			else if(n.compareTo(b) > 0){
				System.out.println("Yougth");
			}
			else System.out.println("Hrdv");
		}
	}
}
