pat-a1022. Digital Library (30)

宝典基础篇终于A完了，后面就是提高篇了。。真鸡冻。基础够了。以后还是希望每天A一个不水的题

这个题就关键字那里开始没认真读坑了一点

#include<iostream>#include<map>#include<string>#include<sstream>#include<cstdio>using namespace std;struct node{	string info[5];	string ke[5];};node k[10010];int main(){	int n;	cin>>n;	string temp;	map<string,int>si;	for(int i=0;i<n;++i){		cin>>temp;		getchar();		for(int j=0;j<5;++j)		 getline(cin,k[i].info[j]);		stringstream ss(k[i].info[2]);		int j=0;		while(ss>>k[i].ke[j]) j++;		si[temp]=i;	}	cin>>n;	getchar();	while(n--){		int ok=0;		getline(cin,temp);		cout<<temp<<endl;		int t=temp[0]-'0';		temp.erase(temp.begin(),temp.begin()+3);		map<string,int>::iterator it=si.begin();		for(;it!=si.end();it++){			if(t!=3){				if(k[it->second].info[t-1]==temp){					cout<<it->first<<endl;					ok=1;				}			}			else{				for(int i=0;i<5;++i)				 if(k[it->second].ke[i]==temp){				 	cout<<it->first<<endl;				 	ok=1;				 }			}		}		if(!ok) cout<<"Not Found"<<endl;	}	return 0;} 
A Digital Library contains millions of books, stored according to their titles, authors, key Words of their abstracts, publishers, and published years. Each book is assigned an unique 7-digit number as its ID. Given any query from a reader, you are supposed to output the resulting books, sorted in increasing order of their ID's.
Input Specification:
Each input file contains one test case. For each case, the first line contains a positive integer N (<=10000) which is the total number of books. Then N blocks follow, each contains the information of a book in 6 lines:
Line #1: the 7-digit ID number;Line #2: the book title -- a string of no more than 80 characters;Line #3: the author -- a string of no more than 80 characters;Line #4: the key words -- each word is a string of no more than 10 characters without any white space, and the keywords are separated by exactly one space;Line #5: the publisher -- a string of no more than 80 characters;Line #6: the published year -- a 4-digit number which is in the range [1000, 3000].
It is assumed that each book belongs to one author only, and contains no more than 5 key words; there are no more than 1000 distinct key words in total; and there are no more than 1000 distinct publishers.
After the book information, there is a line containing a positive integer M (<=1000) which is the number of user's search queries. Then M lines follow, each in one of the formats shown below:
1: a book title2: name of an author3: a key word4: name of a publisher5: a 4-digit number rePResenting the year
Output Specification:
For each query, first print the original query in a line, then output the resulting book ID's in increasing order, each occupying a line. If no book is found, print "Not Found" instead.
