Problem Statement for "InsideOut"

Problem Statement

Your printer has been infected by a virus and is printing gibberish. After staring at several printed pages for a while, you realize that it is printing every line inside-out. In other words, the left half of each line is being printed starting in the middle of the page and proceeding out toward the left margin. Similarly, the right half of each line is being printed starting at the right margin and proceeding in toward the middle of the page. For example, the line 

    THIS LINE IS GIBBERISH
is being printed as 
    I ENIL SIHTHSIREBBIG S
