+**Command line program for polynomial factorization mod p^n**

+## :clipboard: Usage Manual
+
+- The user selects an option from the menu: 2 = factorization, 1 = helper, 0 = exit
+- After selecting the factorization, the user is prompted to enter any prime number and then a positive integer greater than 1 (this positive number determines the extension of the finite field *GF(p^n)*).
+- In the next step, it is necessary to enter the mononic polynomial, which we will factorize.
+- The screen displays an evaluation of whether the entered polynomial is reducible or irreducible.
+- In the case of a reducible polynomial, the user is provided with a list of factors in a readable form as well as in a format provided by the [NTL](https://libntl.org/) library.

+
+### Help
+- If the user selects a help option from the main menu, examples of the polynomial format used by the application are displayed.
+- As we can see, the coefficients belonging to *x^0* to *x^n* are written in square brackets in this order.
