Palindrome or Reverse Integer | Dataford Interview Questions

Write a program to reverse an integer or check if a string is a valid palindrome.

Implement reverse_integer_or_is_palindrome(value). If value is an integer, return its digits reversed while preserving its sign. If value is a string, return True when it is a palindrome after ignoring case and non-alphanumeric characters, otherwise return False.

Constraints

value is either an integer or a string
For integer input, the value fits within Python's integer range
For string input, 0 <= len(value) <= 10^5
Palindrome comparison is case-insensitive and ignores non-alphanumeric characters

Function Signature

def reverse_integer_or_is_palindrome(value):
