Email Address Validation

You are given a single email address as input. Your task is to determine if the email address is valid based on the following criteria:

• The email must contain exactly one '@' symbol.
• The local part (the part before '@') must be non-empty and consist of only alphanumeric characters (i.e. letters and digits).
• The domain part (the part after '@') must be non-empty, contain at least one dot ('.'), and the dot cannot be the first or last character of the domain.
• The domain part may only consist of alphanumeric characters and dots.
• The email address is considered case-insensitive.

If all the conditions are met, print true; otherwise, print false.

Note: Your program should read from standard input and write to standard output.
