Write a method named isValidPassword that takes a string as input parameter, and returns true if that string represents
a valid password, or false otherwise. A password is considered valid if (and only if) its length is between 6 and 8
characters (inclusive), and all of the requirements below are satisfied. You must use regular expressions to check if
the following conditions are met:
• The password starts either with an upper case letter or with one of the following special characters: ! @ #
• The password’s first character is followed by at least 5, and at most 7, word characters (i.e., letters, digits,
or underscore)
• The password’s last character is not equal to any of the following special characters: * . %
• The password does not contain any whitespace characters
