Puzzle $1$

Create a markdown cell with a level $2$ header that reads "Puzzle $1".$ Add unformatted text explaining that you will test your

function on the puzzle whose initial state is stored in the file puzzle$01.$txt$,$ and that you will begin by loading the puzzle

from the file.

Use load$\_$puzzle$()$ to load the contents of puzzle$01.$txt into a list named puzzle$01.$ Use display$\_$puzzle$()$ to

print the puzzle.

Add a markdown cell explaining that you will now attempt to find a solution to the puzzle.

Use solve$()$ to attempt to find the solution of the puzzle stored in puzzle$01.$ If a solution exists, then use

display$\_$puzzle$()$ to print the solution. Otherwise, print the text $"$No solution exists for this puzzle."
