Please help me with the first two tests.

Problem 2 - Passphrase Check (40 points) We are trying to make sure your passphrase is acceptable! Write a script that asks for an input string that will be used as your password. 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 'fh,@s@h'f" 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 (i.e. no alphabetic, punctuation, or special characters). Third Function: For the third word, you must check if it starts with one of these special characters ("@", "$", "%, "", "&"), ends with a punctuation mark only commas (). periods (), 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".
