- | Long ago, in ancient Rome, Julius Caesar is said to have used simple ciphers | ||
- | to encrypt messages that he wanted to stay secret. | ||
- | The following problems are based on a modified version of this same cipher. | ||
- | Caesar started by writing out the alphabet and pairing each letter to a number that would represent it. | ||
- | One such pairing is | ||
- | $$ | ||
- | \begin{array}{|c|c|c|c|c|} | ||
- | a& | ||
- | 1& | ||
- | \end{array}. | ||
