This looks deceptively easy. My code (which I believe is as short as possible) is 11 characters. (Perhaps this is unfair -- it's more like a "who can hit the ball where I hit it" challenge than a "who can hit the ball far" challenge.)

Goal: create a function that takes a list of strings as its arguments and returns the characters of those strings in reversed order. That's it!

print R(123);       # 321
print R(12,34,56);  # 654321
sub R {...}         # <-- my best score: 11

More than meets the eye. I'm betting a handful of you get an answer of 14 characters, but there might be a couple who slip through and figure out the trick to save a character, and another few to get it down to 11.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
