Question: A website requires the users to input username and password to register. 
Write a program to check the validity of password input by users. Following are the criteria for checking the password:

At least 1 letter between [a-z]
At least 1 number between [0-9]
At least 1 letter between [A-Z]
At least 1 character from [$#@]
Minimum length of transaction password: 6
Maximum length of transaction password: 12 
Your program should accept a sequence of comma separated passwords and 
will check them according to the above criteria. Passwords that match the criteria are to be printed, each separated by a comma. 
Example If the following passwords are given as input to the program: ABd1234@1,a F1#,2w3E*,2We3345 Then, the output of the program should be: ABd1234@1
Hints: In case of input data being supplied to the question, it should be assumed to be a console input.
