WebAug 13, 2013 · We know that count (1) = 0 (because the string is too short), count (2) = 1 (00) and count (3) = 3 (000, 001, 100). So we can start an iteration, and let's try for n=4 (where you already have the result): count (4) = 2*count (3) +2^1 - count (1) = 2*3 + 2 - 0 = 8 Share Follow answered Aug 13, 2013 at 17:07 Ingo Leonhardt 9,102 2 23 33 Add a comment
