Table of n, a(n) for n=1..82.

EXAMPLE

a(1)=1; a(2)=0.

n=3, binary 11. {1,1} is not a part of {1,0} thus a(3)=0.

n=4, binary 100. {1,0,0} is a part of {1,0,0} thus a(4)=1.

n=5, binary 101. {1,0,1} is not a part of {1,0,0,1} thus a(5)=0.

n=6, binary 110. {1,1,0} is not a part of {1,0,0,1,0} thus a(6)=0.

n=7, binary 111. {1,1,1} is not a part of {1,0,0,1,0,0} thus a(7)=0.

and so on.
