If 'BEAUTIFUL' is coded as 'ADZTSHETK' in some coding scheme, then how will 'HANDSOME' be coded in the same scheme?

HANDSOME becomes GZMCRNLD.

Comparing BEAUTIFUL with ADZTSHETK, each letter shifts back by 1.

H-1 = G, A-1 = Z, N-1 = M, D-1 = C.

S-1 = R, O-1 = N, M-1 = L, E-1 = D.

Joining gives GZMCRNLD.
