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

 

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

 

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

 

Sample Input

 
START from fiwo hello difh mars riwosf earth fnnvk like fiiwj END START difh, i'm fiwo riwosf. i fiiwj fnnvk! END

 

Sample Output

 
hello, i'm from mars. i like earth!
Hint
Huge input, scanf is recommended.

OK! from now on, I will try to write in English, just for some pratice, because it will be a CET-4 in next term.
When you guys look at the simple input and simple output, i think you have already know we must use Trie to solve this problem.
So the next step is simple , just"TYPE ATire".
But at this time, i try anotherway to plant this tree!!!!So we haveTHREE Trie style!!!!!!!!!!
The new way's core is the "Pointer point to the Pointer". I will talk about it in detail in another post.
After you have planted the Trie, we must deal with the sentence. In my own way, easily,just use the function "isalpha()" which in "cctype", to seperate the lowcase from other characters.
So, Here is the code: 生气

It's not so hard all the way~~~RIGHT?!
一、综合实战—使用极轴追踪方式绘制信号灯 实战目标:利用对象捕捉追踪和极轴追踪功能创建信号灯图形 技术要点:结合两种追踪方式实现精确绘图,适用于工程制图中需要精确定位的场景 1. 切换至AutoCAD 操作步骤: 启动AutoCAD 2016软件 打开随书光盘中的素材文件 确认工作空间为"草图与注释"模式 2. 绘图设置 1)草图设置对话框 打开方式:通过"工具→绘图设置"菜单命令 功能定位:该对话框包含捕捉、追踪等核心绘图辅助功能设置 2)对象捕捉设置 关键配置: 启用对象捕捉(F3快捷键) 启用对象捕捉追踪(F11快捷键) 勾选端点、中心、圆心、象限点等常用捕捉模式 追踪原理:命令执行时悬停光标可显示追踪矢量,再次悬停可停止追踪 3)极轴追踪设置 参数设置: 启用极轴追踪功能 设置角度增量为45度 确认后退出对话框 3. 绘制信号灯 1)绘制圆形 执行命令:"绘图→圆→圆心、半径"命令 绘制过程: 使用对象捕捉追踪定位矩形中心作为圆心 输入半径值30并按Enter确认 通过象限点捕捉确保圆形位置准确 2)绘制直线 操作要点: 选择"绘图→直线"命令 捕捉矩形上边中点作为起点 捕捉圆的上象限点作为终点 按Enter结束当前直线命令 重复技巧: 按Enter可重复最近使用的直线命令 通过圆心捕捉和极轴追踪绘制放射状直线 最终形成完整的信号灯指示图案 3)完成绘制 验证要点: 检查所有直线是否准确连接圆心和象限点 确认极轴追踪的45度增量是否体现 保存绘图文件(快捷键Ctrl+S)
