Positive numbers (7 - 10 min) Check that each value in the matrix is a positive number. Create formatted output for the number of nonpositive (≤ 0) values found. For each nonpositive value, prompt the user to replace it with a positive whole number. If the user does not enter a valid number, continue prompting the user until a positive whole number is entered. Once the entire matrix has been checked, save the matrix to MA6_Task3.csv.

 

 TASK 4: Determine magic square classification (10 - 20 min) Determine if the matrix is a form of magic square. Each criterion below defines a classification of magic square. If none of the criteria are met, produce a warning informing the user that they have not entered a magic square, and ask the user if they wish to try entering a new matrix. Rerun the entire program if the user chooses to enter a new matrix. 

Determine the classification of the magic square using the following requirements:

- 1. If each row and column sum to the same value (the magic constant), the magic square is classified as "semi-magic"

 2. If, in addition to criterion 1, both diagonals sum to the same value as the rows and columns, the magic square is classified as "normal" 

3. If, in addition to criteria 1 and 2, the values in the square are only the sequence of numbers from 1 to ???? 2 (for example, the values in a 3x3 square would be 1:9, and for a 4x4 square would be 1:16), the magic square is classified as "perfect"
