Intoduction 引入

If you ever tried to read a html document on a Macintosh, you know how hard it is if no Netscape is installed.
Now, who can forget to install a web browser? This is very easy because most of the times you don't need one on a MAC because there is a Acrobate Reader which is native to MAC. But if you ever need one, what do you do?

如果您曾尝试在Macintosh上阅读html文档，那么您知道如果没有安装Netscape，那么它是多么的困难。
现在，谁可以忘记安装网络浏览器？ 这是非常容易的，因为大多数时候，您不需要在MAC上，因为有一个Acrobate Reader是本机MAC。 但如果你需要一个，你做什么？

Description 描述

Your task is to write a small html-browser. It should only display the content of the input-file and knows only the html commands (tags)<br>which is a linebreak and<hr>which is a horizontal ruler. Then you should treat all tabulators, spaces and newlines as one space and display the resulting text with no more than 80 characters on a line.

你的任务是写一个小的html浏览器。 它应该只显示输入文件的内容，只知道html命令（标签）<br>它是一个换行符，而<hr>是一个水平标尺。 然后，您应该将所有制表符，空格和换行符视为一个空格，并在一行上显示不超过80个字符的结果文本。

I/O Formats 交互格式

Input 输入

The input consists of a text you should display. This text consists of words and HTML tags separated by one or more spaces, tabulators or newlines.
A word is a sequence of letters, numbers and punctuation. For example, "abc,123" is one word, but "abc, 123" are two words, namely "abc," and "123". A word is always shorter than 81 characters and does not contain any '<' or '>'. All HTML tags are either <br> or <hr>(No space between).

Every test data is promised that can be displayed in Chrome.

输入由您应显示的文本组成。 该文本由一个或多个空格，制表符或换行符分隔的单词和HTML标签组成。
一个字是一系列字母，数字和标点符号。 例如，“abc，123”是一个单词，但是“abc”123是两个单词，即“abc”和“123”。 一个字总是短于81个字符，不包含任何'<'或'>'。 所有HTML标签都是<br>或<hr>（之间没有空格）。
允许每个测试数据都可以在Chrome中显示。

Output 输出

You should display the the resulting text using this rules:
•If you read a word in the input and the resulting line does not get longer than 80 chars, print it, else print it on a new line.
•If you read a <br>in the input, start a new line.
•If you read a<hr>in the input, start a new line unless you already are at the beginning of a line, display 80 characters of '-' and start a new line (again).
The last line is ended by a newline character.

您应该使用此规则显示生成的文本：
•如果您在输入中读取一个单词，并且生成的行不会超过80个字符，请打印，否则将其打印在新行上。
•如果您在输入中读取了<br>，请启动新行。
•如果您在输入中读取<hr>，请开始新行，除非您已经在行的开头，显示80个字符的' - '并再次启动新行。
最后一行以换行符结尾。
