	string x;
	int i,temp;
	vector<string>data;
	while (in>>x) data.push_back(x);
	sort(data.begin(),data.end());
	temp=0;
	for (i=0;i<data.size()-1;i++)
	{
		if (data[i]==data[i+1]) temp++;
		else 
		{	
			out<<"单词 "<<data[i]<<"出现次数为："<<temp+1<<"次"<<endl;
			temp=0;
		}
	}
	out<<"单词 "<<data[data.size()-1]<<"出现次数为："<<temp+1<<"次"<<endl;
	return 1;
