Time it Took Matthew
About 40 minutes but I forgot to time myself this time :(
What to submit
A zip file containing

1. A Makefile that will compile your code into a an executable named
   find_determinant.out
2. All of your source files for your answer (.c and .h files)
   Make sure to not accidentally zip the folder that contains your answer but instead the files
   themselves.

   Problem Description
   Write a program to find the determinant of a matrix. For how to find a determinant of a matrix
   please see: https://www.mathsisfun.com/al... Here you can find a
   determinant calculator to help you check your work:

   Problem Details
3. The name of the file containing the matrix will be given on the command line
   a. This name will always be valid
4. The structure of a matrix file is
   Num_rows num_cols
   row1_val1 row1_val2 row1_val3…
   row2_val1 row2_val2 row2_val3…
   ...
5. The files will always be structured correctly
6. Examples of these files have been included in the starter code
7. The matrices will always be square, ie N X N
8. The values in the matrix are real numbers
   Additional Requirements
9. You should always print your answer to 2 decimal places
10. You must use a struct to represent your matrix object
    a. If you do not use a struct the TAs will manually deduct 50% from your score after
    the due date has passed
11. Your solution should consist of at least 3 source files
    a. matrix.c
    b. matrix.h
    c. main.c
    Hints
12. This problem is recursive
13. Make sure to only open the file in read (“r”) mode. If you open it in read and write (“r+”)
    mode or write (“w”) mode you will get an error as you only have read permissions for the
    matrix files
14. You are free to write as many functions as you want, so take advantage of that fact and
    break the problem down into lots of steps
    Example
    In the following example, input has been underlined to help you tell it apart from what you
    should output. You don’t need to underline anything, it is just a visual aid for you.
    Assume the file 3X3Matrix.txt had the following contents
15. 3
16. 2 3
17. 5 6
18. 8 9
    ./findDeterminant.out 3X3Matrix.txt
    The determinant is 0.00.
