 A182101 Random walk determined by the binary digits of the Dottie number, A003957. 1
 0, 1, 0, 1, 2, 3, 4, 3, 4, 3, 2, 3, 4, 3, 4, 3, 2, 3, 2, 3, 2, 3, 4, 5, 4, 5, 6, 7, 6, 7, 8, 7, 6, 5, 4, 3, 4, 5, 6, 7, 6, 5, 6, 7, 8, 7, 6, 5, 6, 5, 6, 7, 6, 7, 8, 7, 8, 9, 10, 9, 8, 9, 8, 9, 8, 9, 10, 9, 10, 9, 10 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,5 COMMENTS Start at a(0)=0. Each 0 in the binary expansion corresponds to a step of -1, while a 1 corresponds to a step of +1. Partial sums of the sequence 2*A121967(n)-1. The first time a(n) is negative is n=93. LINKS G. C. Greubel, Table of n, a(n) for n = 0..5000 EXAMPLE a(5)=3, and the sixth bit of the Dottie number is 1, so a(6)=4. On the other hand, the seventh bit of the Dottie number is 0, so a(7)=3.
