此题用queue广搜也行,只不过要用G++编译,用C++来编译就会TLE

Posted by zengjing at 2011-09-02 21:42:46 on Problem 1426
我的代码,里面也有深搜的代码
#include <iostream>
#include<string>
#include <fstream>
#include <queue>
using namespace std;
//void DFS(long long k,int level);
int n;
long long result=0;
bool flag;
int main(int argc,char** argv)
{
//	if(argc!=2)return 1;
//	ifstream infile(argv[1]);
	
	
	while(cin>>n,n)
	{
		//深搜代码
		/*flag=false;
		DFS(1,1);
		if(flag)
		cout<<result<<endl;*/
		//广搜代码
		queue<long long > myQueue;
		myQueue.push(1);
		while(!myQueue.empty())
		{
			long long front=myQueue.front();
			myQueue.pop();
			if(front%n!=0)
			{
				myQueue.push(front*10);
				myQueue.push(front*10+1);
			}
			else
			{
				cout<<front<<endl;		
				break;
			}
				
		}

	}
	system("pause");
}
/*void DFS(long long  k,int level)
{
	if(flag)
		return ;
	if(k%n==0)
	{
		result=k;
		flag=true;
		return ;
	}
	if(level==19)
		return ;
	DFS(k*10,level+1);
	DFS(k*10+1,level+1);
}*/
