This input string will have three words' separated by a space character. Each of these words has specific requirements, listed below. You must write a function for each requirement (three total functions). Make sure your functions follow the original template that provided. First Function: For the first word, you must check if it is a palindrome (it is the same forward and backward, like 'glolg' or 'tacocat"), is case-insensitive (so "GfraaRFg" or "Vobov' are valid), and only uses alphabetical letters ('tre3ert' and "h@s@hf" are not valid). Second Function: For the second word, you must check if it is a positive integer with at least 4 digits, containing only numeric characters (ie. no alphabetic, punctuation, or special characters) Third Function: For the third word, you must check if it starts with one of these special characters ('@'S". "X","8) ends with a punctuation mark (only commas (.). periode (), exclamation marks ("") and question marks (?) are allowed), and has three letters in between the special character and punctuation mark (e.g. '@dog" or "Stpb? or cat If the entire password meets all the correct specifications, then print valid", otherwise, print 'invalid" Template Functions (DO NOT CHANGE FUNCTION NAMES): det palindrome (): def integer () def special(); det special
