A website requires that passwords only contain alphabetic characters or numbers. For each character in keyString that is not an alphabetic character or number, replace the character with $\text{'}1\text{'},$

Ex: If the input is then the output is:

Updated password: $4s190$

Note:

isalpha$()$ returns true if a character is alphabetic, and false otherwise. Exi isalpha$(\text{'}$a$\text{'})$ returns true. isalpha$(\text{'}8\text{'})$ returns false

isdigit$)$ returns true if a character is a digit, and false otherwise. Exi isdigit$(\text{'}8\text{'})$ returns true isdigit$(\text{'}$a$\text{'})$ false.
