Kata

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
