Problem C

 

Portable Password Purse

 

Input File: c.in

 

Web-based transactions need users to login with a user-name and password pair. The proper choice of password is critical for one's personal data security. However, with more websites requiring users to create a user-name and password pair, users often reuse passwords from another site or worse, use a dictionary-based password so it will be easy to remember.

 

Abigail Christine Mann, or ACM for short, devised a portable password purse. The purse, however, is virtual - passwords are not written on a piece of paper or a notebook nor are passwords saved and protected by software. The purse is made up of algorithms that ACM associates with each website that she registers with.

 

ACM devised three basic algorithms to determine a particular web site's password. She drops the top-level domains (TLD) such as .edu, .com, .edu.ph, .com.sg, etc., and then follows the algorithms below.

 

1. If the domain name has less than 6 characters, append capitalized initials in between each character and replace all vowels (except the one from initials) to its numeric equivalent in the alphabet.

 

Example:

 

     apple.com

     = aApCpMle

     = 1ApCpMl5 (password)

 

2. If the domain has an even number of letters, split the domain into two, add '%' at the middle, transpose the first set of letters using the rules below and the second set of letters are converted to alternating upper and lower case characters.

 

s = $, l = 7, e = 3, i = !, g = 6, o = 0

 

 

 

Example:

 

     blogspot.com

     = blog%spot

     = b706%SpOt

 

3. If the domain has an odd number of letters, split the domain into two, replace the middle character with '_', transpose the second set of letters using the table above and the first set of letters are converted to alternating upper and lower case characters.

 

Example:

 

     microsoft.com

     = micr_soft

     = MiCr_$0ft

 

The task is to determine the passwords for each of the web-site on the list. The list is provided as a text file, with each site listed on each line.
