Caesar Cipher Encoder For the first part of the exam, implement a Caesar cipher encoder. Your program should (1) take as inputs the message to encrypt and the shift and (2) output the final encrypted message. A couple of notes:  Only letters should be shifted, do not shift symbols, numbers, spaces, or anything except letters.  Capitalization should be retained.  Your program should be able to handle both positive and negative shifts. Your program should efficiently handle shifts larger than 26 and smaller than -26 (ie., you should not go around the alphabet multiple times) Part 2: Brute Force Caesar Cipher Breaker For the second part of the exam, implement a brute force Caesar cipher breaker. A brute force method is one that checks every possible option and chooses the best one. Your program should (1) take as input a message that has been encoded using a Caesar Cipher and (2) output the original message. A couple of notes  Capitalization should be retained.  To simplify, there will not be any punctuation in the encoded message. That is, the input will consist of only words separated by spaces . You are NOT given the shift. Instead, try every possible shift and use this dictionary.txt file to decide on the most likely original message. THE RULES: You are allowed to use resources on this exam such as zyBooks, python videos, and your own previous notes and work. You are welcome to use the Internet to look up specific syntactic questions, but you should NOT copy paste a chunk of code from the Internet. ANY sources used should be cited in your References section. We will be running all solutions against our plagiarism software (which will include similar code found online). For example, you can use the Internet to get help in writing a for loop: you should NOT use the Internet/open forums to find solutions to Caesar Cipher! Cheating on an exam is a BIG deal. You would be wise to follow the rules. Example Execution #1 Input the message to encrypt and the desired shift. MESSAGE> Hello world! SHIFT> -9485 Your encrypted message with shift -9485: OUTPUT Magt stwi! MESSAGE_TO_DECRYPT> Z fevdecp jnvri kyrk z rd lg kf ef xffu The original message is: OUTPUT I solemnly swear that I am up to no good Comments All Python files should include a header with your name, section, assignment info, references (i.e., what resources did you use?), and approximate time taken to do the assignment. Be sure to cite any allowed external references used to complete the assignment. Any code without this header will lose 1 point. Here's an example: # John Henke # CSCI 101 - Section D # Python Exam # References: my code from Python Lab 7 # Time: 55 minutes
