  • 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 HTML 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?
    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.
  • 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>.
  • 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.
  • 样例输入
  • Hallo, dies ist eine 
    ziemlich lange Zeile, die in Html
    aber nicht umgebrochen wird.
    <br>
    Zwei <br> <br> produzieren zwei Newlines. 
    Es gibt auch noch das tag <hr> was einen Trenner darstellt.
    Zwei <hr> <hr> produzieren zwei Horizontal Rulers.
    Achtung       mehrere Leerzeichen irritieren
    
    Html genauso wenig wie
    
    
    mehrere Leerzeilen.
