Let P(k) = floor(k/2). Start with n, apply P repeatedly until reaching 0. a(n) = concatenation of the differences of the successive numbers obtained. - David Wasserman (wasserma(AT)spawar.navy.mil), Oct 25 2004

EXAMPLE
|
11 -> 5 -> 2 -> 1, hence a(11) = 6311.
11 -> 5 -> 2 -> 1 -> 0, hence a(11) = 6311.
