A binary string is a word containing only Os and 1s. In a binary string, a 1-run is a non-extendable substring containing only 1s. Given a positive integer n, let B(n) be the number of 1-runs in the binary representation of n. For example, B(107) = 3 since 107 in binary is 1101011 which has exactly three 1-runs. What is the following expression equal to? B(1) + B(2) + B(3) + ... + B(255)

Transcribed Image Text:A binary string is a word containing only Os and 1s. In a binary string, a 1-run
is a non-extendable substring containing only 1s. Given a positive integer n,
let B(n) be the number of 1-runs in the binary representation of n. For
example, B(107) = 3 since 107 in binary is 1101011 which has exactly three
1-runs. What is the following expression equal to?
B(1) + B(2) + B(3) + ... + B(255)
