Problem Description

A cryptogram is piece of text that has been passed through a simple cipher that maps all instances of one letter to a different letter. The familiar rot13 encoding is a trivial example.

A solution to a cryptogram is a one-to-one mapping between two sets of (up to) 26 letters, such that applying the map to the cryptogram yields the greatest possible number from words in the dictionary.

Three unsolved cryptograms given. Each cryptogram uses a different cipher. The cryptograms may contain a few words that are not in the dictionary.

Theres a dictionary in the root of this repository you can use.

Story - Detect cipher

As a user, when I provide a cryptogram
I want to detect the most likely cipher
So I can crack codes!

    Accept: Translation output
            Translation with most valid detected words choosen

Story - Output cipher

As a user, when detect a cipher
I want to output the cipher results to the screen
So I can see which letters correspond in my match

Accept: Cipher matches output

Examples

Given this cryptogram

gebo tev e cwaack cegn gsatkb ussyk

Output is

Best match: mary had a little lamb mother goose

Cipher
abcdefghijklmnopqrstuvwxyz
trl.a.m...e..by...ohgdi.s.
