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.
