I just discovered that two of my CAs, Alice and Bob, have been secretly communicating with each other in our common group chat that we use for course matters. I am pretty sure they make use of one-time pad encryption with the following parameters: The message space consists of English messages which are 33 characters long, where only letters (of either case), spaces and possibly punctuation marks are used. Please help me break their code!

(1) Below are eleven ciphertexts (in hex format) that they exchanged just minutes ago today... (Friday, Feb 3, 2023):

** Write down the 11 plaintext messages that were exchanged. You may write a program that will help you with your cryptanalysis. In designing your program, remember that most likely spaces will be among the most frequent characters in the plaintexts, and carefully observe what their role may be in the mapping from plaintexts to ciphertexts. Some of the exercises from lab might help! Also note that even once. Explain what your cryptanalysis strategy is and what algorithm your program implements.
