In a certain code language, 'PAINTS' is written as 'HGMRZK' and 'ROCKY' is written as 'BPXLI'. How will 'HUNTER' be written in that language?

First the letters of each word are changed to it's opposite letter and after that obtained letters will be written such as first and last letters are interchanged. Similarly second and second last letters are interchanged and so on...

A B C D E  F G H I  J  K  L M

Z Y X W V U T  S R Q P O N

PAINTS ==> KZRMGH ==> HGMRZK

ROCKY ==> ILXPB ==> BPXLI

HUNTER ==> SFMGVI ==> IVGMFS

So 'HUNTER' will be coded as 'IVGMFS' in that code language.
