%N A082410 a(1)=0 and a(n) is built with the rule: for any k>=0, if a(1),a(2),......,
               a(2^k+1) are known next 2^k terms are given as follows: a(2k^+1+i)=1-a(2^k+1-i) 
               for 1<=i<=2^k
%C A082410 It seems that a(n) is A014577 shifted right twice.
%C A082410 Complement of characteristic function of A060833.
%F A082410 n>=2 sum(k=1, n, a(k))=(n+A037834(n-1))/2
%e A082410 3 first terms are 0,1,1 therefore a(4)=a(3+1)=1-a(3-1)=1-a(2)=0, a(5)=a(3+2)=1-a(3-2)=1-a(1)=1 
               and sequence begins 0,1,1,0,1,...
