Secret Code
The following string of text has a secret code encrypted inside it:
xmydartlkarrsgeoptwwjvbodeblxgbleivetoihewt
In order to decipher it, you will need to:
1) Extract every fourth letter of the string
2) Reverse the order of the extracted letters
3) Set the case of the extracted letters so that they alternate between uppercase and lowercase, with the first letter being uppercase.
The solution will require the following elements:
1) You will need three string variables: - one called "message" to store the above string to be deciphered - one called "result1" to store the result after Step 1 - one called "secretCode" to store the results after Step 2 and 3
2) The length(), charAt(), toUpper(), and toLower() methods
3) String concatenation
4) The mod operator
