# Introduction In this challenge, we will be implementing encryption and decryption operations based on a set of encryption rules. The encryption rules involve moving the ASCII code of each character in the plaintext forward by a certain length, reversing the result characters, and then moving the ASCII code backward by another length. Our task is to design a program that can perform these encryption and decryption operations based on the given rules. We have a code template provided, and we need to complete the code in the designated areas to meet the requirements of the challenge.
