%N In the number n, replace all (decimal) digits '0' with '1' and vice versa.

%C The map which is applied to primes in A171013 and A175791.

%H Vincenzo Librandi, <a href="/A222210/b222210.txt">Table of n, a(n) for n = 0..1000</a>

%t a[n_] := IntegerDigits[n] /. {0 -> 1, 1 -> 0} // FromDigits; Table[a[n], {n, 0, 75}] (* _Jean-Fran├žois Alcover_, Jun 11 2013 *)

%o (PARI) A222210(n,d=[1,0,2,3,4,5,6,7,8,9])=sum(i=1,#n=digits(n),d[n[i]+1]*10^(#n-i),!n) \\ N.B.: PARI's digits() function returns [] for 0.

%Y Cf. A171013, A175791; A048380.
