Assembly language instructions frequently are in the form of a word that represents the operator and then the operands separated by a comma. For example, the string ‘ADD n,m’ is an instruction to add n + m. Write a function called assembly_add that will receive a string in this form and will return the sum of n + m. For example,

Cryptography, or encryption, is the process of converting plaintext (e.g., a sentence or paragraph) into something that should be unintelligible, called the ciphertext. The reverse process is code-breaking, or cryptanalysis, which relies on searching the encrypted message for weaknesses and deciphering it from that point. Modern security systems are heavily reliant on these processes.
