There is one encryption algorithm called Affine Cipher, with encryption function ??(??) = (???? + ??) mod 26. Here, x is the numerical equivalent of the given plaintext letter, a and b are appropriately chosen integers.

Consider an affine cipher (mod 26). You are doing a chosen plaintext attack using lalala and the cipher text is popopo. Determine the encryption function with explanation of the steps.
