This is a simple puzzle to get you used to reading in and working with 2-d arrays (arrays of arrays). It’s good practice to separate out the code you use to initialize and manipulate a data structure, and that’s especially true in these exercises. All of the 2-d arrays in these puzzles will be square or rectangular. A list of the functions you should develop for reuse are listed below the puzzle.

Puzzle

Write a program that can read open a file and read the contents into a 2-d array. The file will contain x’s and 2 o’s. your program should take a file name and output directions on how to get from one o to the other. Sample input:

xxxxxxxxxxxxxx
xxoxxxxxxxxxxx
xxxxxxxxxxxxxx
xxxxxxxxxxoxxx
xxxxxxxxxxxxxx

sample output: right 8, down 2
