In a code language, 'LEATHER' is written as 'NGCGFCP' and 'JASMINE' is written as 'LCUNGLD'. How will 'PHYSICS' be written in that language?

The logic followed here is: The first three letters are written as the second succeeding letter, the 4th letter is written as its opposite letter and the last three letters are written as their second preceding letter as per the English alphabetical series. L          E         A         T          H         E         R + 2       +2        +2        OPP.   -2         -2         -2 N         G         C         G         F          C         P So, 'LEATHER' is written as 'NGCGFCP'. J          A         S         M         I           N         E + 2       +2        +2        OPP.   -2         -2         -2 L          C         U         N         G         L          D So, 'JASMINE' is written as 'LCUNGLD'.
