In this there should be a shift over K = 5 but the example below is K = 3. This should result in actual character and not the control ASCII represenations.

- Decrypt a message that was encrypted using the following logic: • First the words in the sentence are reversed. For example, "welcome to hackerrank" becomes "hackerrank to welcome" • For each word, adjacent repeated letters are compressed in the format <character><frequency>. For example, "mississippi" becomes "mis2is2ip2i" or "baaa" becomes "ba3". Note the format is not applied for characters with frequency 1.

Write an ARM assembly program to use ciphers. See the steps below to implement the cipher. In this program you will implement a Symmetric Encryption. a) Assign a variable name “Choice” with value 0 or 1 to show the choice for encryption or decryption. 0 for encrypt and 1 for decrypt. . b) If we assign 0 to the variable choice the program will do encryption and if its 1 the program will do decryption. c) For encryption design a key value, for that assign your last nonzero number of your number in a variable called “Key” Example: if your number is 5012345 Assign 5 to the variable Key and use it as the Key for encryption. d) For choice 0 store the Cipher in a variable called “C”, for choice 1 store the Plain text in a variable called “P” (use symmetric Key cryptography and implement that for encryption and decryption). e) Test the encrypt program using the first letter of your name in capital case and to test decryption use the…
