Secret Message

This problem was inspired by Project Euler Problem 185.

Encrypting and decrypting messages has been a long standing use of a supercomputer of the day. While not not a state secret cipher, this problem provides a message in a message in a message to uncover. The moral of the story is while there is a well established place for high level highly abstracted languages, algorithmic and performance issues may sometimes dictate other solutions. This problem challenges you to discover algorithm(s) to simplify and solve a well defined logic puzzle, given that for a contest lasting only a few hours, a brute force algorithm could take days of run-time to complete.

This problem is like the Project Euler 185 (Number mind) problem, except instead of numbers, lowercase letters are used. The integer following each sequence of 15 letters reflects the number of right characters, in the right position.

This problem could have 0, just 1, or possibly many solutions
