 OFFSET 1,2 COMMENTS A165316(n) + A165317(n) = the number of digits in the binary representation of n. LINKS EXAMPLE 184 in binary is 10111001. There are exactly three binary digits (the first and last 1's, and the leftmost 0) that are each not adjacent to a similar digit. So a(184) = 3. CROSSREFS Cf. A165316.
