"""
You're on your way to the market when you hear beautiful
music coming from a nearby street performer. The notes come
together like you wouln't believe as the musician puts
together patterns of tunes. As you wonder what kind of
algorithm you could use to shift octaves by 8 pitches
or something silly like that, it dawns on you that you
have been watching the musician for some 10 odd minutes.
You ask, "How much do people normally tip for something
like this?" The artist looks up. "Its always gonna be about
tree fiddy."

It was then that you realize the musician was a 400 foot tall
beast from the paleolithic era. The Loch Ness Monster almost
tricked you!

There are only 2 guaranteed ways to tell if you are speaking
to The Loch Ness Monster: A.) It is a 400 foot tall beast
from the paleolithic era B.) It will ask you for tree fiddy

Since Nessie is a master of disguise, the only way accurately
tell is to look for the phrase "tree fiddy". Since you are
tired of being grifted by this monster, the time has come
to code a solution for finding The Loch Ness Monster.

Note: It can also be written as 3.50 or three fifty.
