/**
 * Description:
 *
 * The marketing team is spending way too much time typing in hashtags.
 * Let's help them with our own Hashtag Generator!
 * Here's the deal:
 *
 * It must start with a hashtag (#).
 * All words must have their first letter capitalized.
 * If the final result is longer than 140 chars it must return false.
 * If the input or the result is an empty string it must return false.
 *
 * Examples
 *
 * " Hello there thanks for trying my Kata"  =>  "#HelloThereThanksForTryingMyKata"
 * "    Hello     World   "                  =>  "#HelloWorld"
 * ""                                        =>  false
 *
