Please write clearly and legibly so I may understand the process. Thank you.

Problem 1: Suppose we modify the Feistel setup as follows. Divide the plaintext into three equal blocks: Lo, Mo, Ro. Let the key for the ith round be K, and let f be some function that produces the appropriate size output. The ith round encryption is given by This continues for n rounds. Consider the decryption algorithm that starts with the ciphertext An, Bn,C and uses the algorithm This continues for n rounds, down to Ao, Bo,G-Show that Ai = Li, Bi-Mi and Ci = Ri for all i, so that decryption algorithm returns the plaintext
