Bit strings of length n
WebHow many bit strings of length n, where n is a positive integer, start and end with 1? Solution. There are n − 2 available slots (the first and the last are occupied with 1), therefore this must be the same number as the number … WebNov 21, 2016 · Now we can take any of the sequence of the valid sequences of length n and add 1 to it and it will be a valid sequence of length ( n + 1). Hence: a n + 1 = a n + b n + c n Now the only way to "construct" a sequence ending in a single zero is to take any of the a n sequences and append 0 to it.

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.
