Any help would be appreciated. There are 26 strings of length 6; 25 of length 5; etc a) How many bitstrings of length 10 contain three consecutive 0’s or 4 consecutive 1’s? (b) How many bitstrings of length 10 contain two sets of 3 consecutive 0’s or two sets of 3 consecutive 1’s? Bits are either 1 or 0, so there are 2 choices per bit, and 8 bits to choose. The GSM charset uses 7-bit alphabet encoding, but the escape characters require 14 bits to encode, thus taking up two characters. Because Base64 is a six-bit encoding, and because the decoded values are divided into 8-bit octets on a modern computer, every four characters of Base64-encoded text (4 sextets = 4*6 = 24 bits) represents three octets of unencoded text or data (3 octets = 3*8 = 24 bits). An optional second argument to rjust() and ljust() will specify a fill character other than a space character. (c) How many bit strings of length 9 are there, such that every 1 is followed immediately by a zero? This is a little bit harder. As we showed in the previous section, string values can contain arbitrary bytes; as we showed in this one, string literals always contain UTF-8 text as long as they have no byte-level escapes. = 10 * 9 * 8 * 7 * 6 / (5 * 4 * 3 * 2 * 1) = 2 * 9 * 2 * 7 = 252 Another way to do this, using the result from part (b), is to recognize that there will be the same number of strings containing at most four 1s and containing at most four 0s, and those two groups contain all the strings that do NOT contain an equal number of 1s and 0s. 1 Oct 2017 10:47 pm First 4 bits can be chosen 2^4 ways except 0000-1- 000, 0001-1-000, 1000-1-000, hence there are only such 13 ways A multiple-choice test contains 10 questions. How many bit strings of length 10 contain a)exactly four 1s? This is just asking us to choose 4 out of 10 slots to place 1’s in. The minimum length of the CHARACTER data type is 1 and it can have a maximum length up to the table page size. Since the short type is a signed one, and contains both positive and negative values, the range of values is between -32 768 and 32 767.
