Using a matrix to store factors’ number

1.Define an int matrix (n * n)
2. Create a static method that print the matrix
2.1 Create a static method that print an array.
3. Create a cicle that insert factors number from a given input (n from 1 to 100) and print all arrays and then insert the array’s elements to a matrix of all factorized number.
