Assume we are given a key K=13 as an encryption key

Assume we are given a key K=13 as an encryption key in Caesar's cipher. 1. What is the result of the following double encryption (C:): 2. C = E (K, E (K, M.)), where M is an arbitrary plaintext element? Explain your answer. 3. How many encryption times will it take with key K=2 before we start observing the same effects as in the previous example with (K=13)
