Declare a Boolean variable named isValidPasswd. Use isValidPasswd to output "Valid" if checkStr contains at least 4 letters and checkStr's length is greater than 7, and "Invalid" otherwise. Ex: If the input is 58m6SF7w, then the output is: Valid Ex: If the input is NKXwLD2, then the output is: Invalid Note: isalpha() returns true if a character is alphabetic, and false otherwise. Ex: isalpha('a') returns true. isalpha('8') returns false.
