Notes:

Each attraction in the output string will be separated by a single comma and space

You will never cross over the same path previously traveled or travel outside of the

matrix dimensions

Do not replace the final location with a $\text{'}$#$\text{'}$ but do replace the initial location with a

$\text{'}$#$\text{'}$

You only alter directions for the attractions you encounter on your path, there may be

extra characters you don't hit

There should not be a comma and space after the last attraction listed in the output

string

You are not guaranteed to visit every attraction, you might not visit any attractions

at all, in which case the outputted sentence would be: 'I went to GT Night at

Six Flags and rode $!\text{'}$
