DECRYPT

In my previous post explaining what it was encrypt. Now I will explain how the process of returning the result code which was encrypted password back to the initial passcode. This process is known as decrypt process.
The algorithm is similar to decrypt the encryption process: 

• Prepare two arrays one for the alphabet and one for the code  

• Then input the code that's encrypted password stored in the variable 'pasw'

•  Then do the process of checking back for instance encrypted code that is '%##^@!' With code array already defined in the array A

•  After that do the returns from the pattern that we have made in the previous encryption process in accordance with my posting of the encryption

Y = Y +26 intended to result from the reduction if J 

(is to return a value that does not produce a negative number)

Code: decrypt
