I was trying to do the practice problems but don't understand what the first beginner or first intermediate problem is asking me to do
Write a program which finds the factorial of a number entered by the user. (check for all conditions) (Beginner).
Create a simple Palindrome checker program. The program should allow the user to enter a string and check whether the given string is a palindrome or not. Only digits and alphabets should be considered while checking for palindromes -- any other characters are to be ignored. (Intermediate)
can someone tell me want a Factorial is or Palindrome
