为啥while(1)就AC，改成while（!s.empty())就WA呢？？
#include <stdio.h>
#include <iostream>
#include <queue>
using namespace std;

int n;
long long bfs()
{
	queue<long long> s;
	long long p;
	s.push(1);
	while(1)//改成while(!s.empty())就WA！！
	{
		p=s.front();
		s.pop();
		if(p%n==0)
			return p;
		s.push(p*10);
		s.push(p*10+1);
	}
}
int main()
{
	while(scanf("%d",&n)&&n!=0)
	{
		long long m=bfs();
		printf("%lld\n",m);
	}
	return 0;
}
