Description: Encrypt this!
You want to create secret messages which can be deciphered by the Decipher this! kata. Here are the conditions:
    1. Your message is a string containing space separated words
    2. You need to encrypt each word in the message using the following rules:
        * The first letter needs to be converted to its ASCII code
        * The second letter needs to be switched with the last letter
    3. Keepin' it simple: There are no special characters in input

Examples:
encrypt_this("Hello") == "72olle"
encrypt_this("good") == "103doo"
encrypt_this("hello world") == "104olle 119drlo"
