MATHEMATICA

a[n_]:= IntegerDigits[n]/.{1->9, 9->1} // FromDigits; Table[a[n], {n, 0, 80}] (* Vincenzo Librandi, Jul 30 2013 *)

PROG

(PARI) A222226(n, d=[0, 9, 2, 3, 4, 5, 6, 7, 8, 1])=sum(i=1, #n=digits(n), d[n[i]+1]*10^(#n-i)) \\ gives correct value for n=0 iff d[1]=0, since digits(0)=[] in PARI (v.2.6)
