Bit strings of length n
Weba) Find a recurrence relation for the number of bit strings of length n that contain three consecutive 0s. b) What are the initial conditions? c) How many bit strings of length seven contain three consecutive 0s? DISCRETE MATH Give an example of a function from N to N that is a) one-to-one but not onto. b) onto but not one-to-one. WebThere are 26 strings of length 6; 25 of length 5; etc. down to 20 strings of length 0 (that’s the empty string). So, alto-gether, that gives 26 + 25 + 24 + 23 + 22 + 2 + 1 = 27 1 = 127 bit strings altogether. 16. How many strings are there of four lowercase letters that have the letter x in them? There are several ways to nd the number.

See Answer WebHow many bit strings of length 10 both begin and end with 1? n. How many bit strings with length not exceeding n, where n is a positive integer, consist entirely of 1s, not counting the empty string? 26+26²+26³+26⁴ = 475,254.
Web(a) Find a recurrence relation for the number of bit strings of length n that contain a pair of consecutive 0s. (i) Step 1: write down a n (The goal: function of n). a n = (ii) Step 2: Find … 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
