Create a Python program that uses the UDP protocol and has servers A, B, and C to incorporate the CRC into your three-node program. A also includes the CRC32 code in the message it sends to B. B gets both this message and the CRC32 code. There is a 40% chance that B will alter the message. B transmits the message and the initial CRC32 code to C. When C receives the message and CRC32 code, it checks to see if it is accurate. NOTE: there should be three files: A.py, B.py, C.py.
