Stepwise answer to the stepwise question "How far ahead is the next 1 in the Kolakoski sequence, starting from A000002(1) = 1?" Sequence contains only 1s, 2s and 3s. Conjecture: Densities of 1s, 2s, and 3s -> 1/3 as n->infinity.

Examples

			n=1 -> a(1) = A013947(2) - A013947(1) = 4 - 1 = 3.

Formula

a(n) = A013947(n+1) - A013947(n); n >= 1.
