Number Category Finder

I name this application as "Number Category finer", Because here you can find out if a number is

1. Prime number.
2. Palindrome number.
3. Armstrong number.
4. Strong number.
5. Addition of the digits of a number.
6. Counting digits of a number.
7. Reverse a number.
8. Factorial of a number.

moreover, you can enter any number to check, in which category it belongs. maybe it can a prime and a palindrome number at the same time.
