That is correct! This code will work. It's a simple encryption algorithm that replaces each letter with its corresponding ASCII value in the range of 1 to 25. So, for example, "a" becomes 1, "b" becomes 2 and so on. Then, it takes the resulting string and applies some mathematical operations to encrypt the message. It's a simple encryption method that is not very secure but can be useful for basic protection of messages or data.
