Answer 1

You remove 0 to 9 from a, b arrays, you can understand it.. It replaces then a with z, b with y,... inversely.. (if you have 1-9 then instead of z, replaces 9, 8 (not y),...
You can say it encoding.., also simple encryption,...

Answer 2

Encoding means converting the input from one form to another.
Encryption is the process of encoding information for example plain text to encrypted text..
Ok. You can say encryption.. (if you have number as output, you can call encoding also..).
Hope it helps to clear it..
