Problem Description

Ignatius is so lucky that he met a Martianyesterday. But he didn't know the language the Martians use. The Martian giveshim a history book of Mars and a dictionary when it leaves. Now Ignatius wantto translate the history book into English. Can you help
him?

 

 

Input

The problem has only one test case, thetest case consists of two parts, the dictionary part and the book part. Thedictionary part starts with a single line contains a string "START",this string should be ignored, then some lines follow, each line contains
twostrings, the first one is a word in English, the second one is thecorresponding word in Martian's language. A line with a single string"END" indicates the end of the directory part, and this string shouldbe ignored. The book part starts with a single line
contains a string"START", this string should be ignored, then an article written inMartian's language. You should translate the article into English with thedictionary. If you find the word in the dictionary you should translate it andwrite the new word into
your translation, if you can't find the word in the dictionaryyou do not have to translate it, and just copy the old word to yourtranslation. Space(' '), tab('\t'), enter('\n') and all the punctuation shouldnot be translated. A line with a single string "END"
indicates theend of the book part, and that's also the end of the input. All the words arein the lowercase, and each word will contain at most 10 characters, and eachline will contain at most 3000 characters.

 

 

Output

In this problem, you have to output thetranslation of the history book.

题解：

字典树，用getline和map解决。注意的是可能会存在特殊字符，或者是符号后面出现的词也在字典里。

源代码：

#include
<iostream>
#include
<stdio.h>
#include
<map>
#include
<string>
#include
<string.h>
using namespace std;
 
map<string,string> dic;
 
int main()
{
   string st,s1;
 
   cin >> st;
   cin >> st;
   while(st!=
"END")
   {
     cin >> s1;
     dic[s1] = st;
     cin >> st;
   }
 
   cin >>st;
   getchar();
   while(getline(cin,st)&& st !=
"END")
   {
     intpos = 0,len = st.length();
     string a;
     while(pos!= len)
     {
       
        if(isalpha(st[pos]))
          a.push_back(st[pos]);
        else
        {
          map<string,string>::iteratorit;
          it = dic.find(a);
          if(it!= dic.end())
             cout<<it->second;
          else
             cout << a;
          cout << st[pos];
          a.clear();
        }
        pos++;
     }
     cout << endl;
   }
   return0;
}
