Description:

---

In Solitaire there is generation of the keystream values. They will be used to encrypt or decrypt the messages. I will be implementing an alogorithm to generate keystream values. The number of keystream values generated will be the same as number of letters in the messages.

Input:

Input will be the message in the form of string. To encode a message with Solitaire,I will remove all non–letters and convert any lower–case letters to upper–case.

Output:

Output will be just the decrypted message — lists of characters without spaces or punctuation.
