Codebreaker

In this activity, you will complete a simple program to decode secret messages!

There are many complex and interesting ciphers for sending coded messages, but here is the simple decoding process for this activity:

• Each number represents the corresponding letter of the English alphabet: 1 = a, 2 = b, 3 = c, ... , 26 = z
• Negative numbers represent uppercase letters: -1 = A, -17 = Q
• All other numbers are ignored
• A non-numeric code indicates the end of each secret message.

You are given some starter code that process encoded messages as input. Now, it's up to you to decipher them!

[HINT: Each message is a single word. Submit the code to see the test cases. Java String class cannot be indexed like an array.

           Use charAt(int index) and toUpperCase() methods if you want to use the number as an index to the ALPHABET String.  ]
