WebYou need a n + b n . From this equation you can easily get that: e n = 1 and f n = n. From the third equation you get c n − 1 = c n − 2 + f n − 2. Using the fourth equation you get c … WebThe first question may have been about strings of length up to n. It is certainly true that the empty string has no bits which are not 1. For the second I would give the answer 0 for n = 0 and the answer 1 for n = 1, as I would argue that the single bit string 1 both starts and ends with a 1 and so should be counted. Share Cite Follow
WebFor a random bit string of length n find the expected value of a random function X that counts the number of pairs of consecutive zeroes. For example X (00100) = 2, X (00000) = 4, X (10101) = 0, X (00010) = 2. Previous question Next … Webn−2 positions, so that we have a n−2 such strings. If a string of length n ends with 00, then, whatever bits are at the first n − 2 positions, such a string already contains a pair of consecutive 0s, and we have 2n−2 such strings. Therefore, we obtain that a n = a n−1 +a n−2 +2 n−2. (b) a 0 = a 1 = 0 since a string of length less ...
