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.

i fiiwj fnnvk!
END
Sample Output
hello, i'm from mars.
i like earth!
Hint
Huge input, scanf is recommended.

題解：
字典樹，用getline和map解決。注意的是可能會存在特殊字符，或者是符號後面出現的詞也在字典裏。
源代碼：
#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;
}
