Weird Text
100 Someone sent me this file (mysterious.txt). It contains only ><+-.,[] symbols and no other letters or numbers.
This mysterious file just has some weird combo of characters "ooooh spooooky"...
...+[>+>+++>+++++++>++++++++++<<<<-]>>>--.<+++++++++.>>----.<...
but I did notice that not all the characters in the list of "><+-.,[]" show up in the line of characters.
This likely means its a special esolang that only uses these characters, some of whcih just did not happen to be in this program. Putting it through the brainfuck interpreter here returns this string of charcaters
