# A Lost Cause
## Description
Pirate Keith loves cryptography and has protected his treasure with a very annoying caesar shift. He has witten
“CGULKVIPFRGDOOCSJTRRVMORCQDZG” on his treasure chest and has left a piece of paper with the following message:
“every subsequent letter is shifted one less than the previous.” Knowing this, can you unlock Pirate Keith’s treasure chest?
## Solution
At first the description was wrong and it said "every subsequent letter is shifted one **__more__** than the previous."
So I trid to shift them back more as the string went down.
And just yield these nonsense.

So I started to think maybe the description was wrong and tried to shift them the other way.
