COMMENTS
The binary plot of the sequence has interesting features (see Illustration in Links section).
EXAMPLE
We have:
n | 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
----------+------------------------------------------------------------------
A345290(n)| 0 -1 2 1 -3 -4 -1 -2 5 4 7 6 2 1 4 3 -8 -9
- so a(0) = 0,
a(2) = 2,
a(1) = 3,
a(5) = 8,
a(4) = 9,
a(7) = 10,
a(6) = 11,
a(3) = 15.
