(b) How many bit strings are there of length 8 … WebI know that a bit string can contain either a 0 or 1 and there are 8 digits. I think I have found a general solution to these types of problems but I do not understand why it works. The answer was 2 8 which was a total of 256 strings. A similar problem with 16 bit strings had a total of 2 16 strings. I do not understand why this is the case.

WebBit Strings. A bit string is a sequence of bits. Bit strings can be used to represent sets or to manipulate binary data. The elements of a bit string are numbered from zero up to the number of bits in the string less one, in right to left order, (the rightmost bit is numbered zero).When you convert from a bit string to an integer, the zero-th bit is associated with … WebHow many bit strings of length 10 contain a)exactly four 1s?

WebNov 2, 2012 · That depends on the length of the string and the encoding used. For example, ASCII encoding uses one byte per character. In ASCII, the number of characters in the string is also its size in bytes. There are 8 bits in a byte. You should also be aware that in C style strings, they are terminated by a \0 character.

But, note we are counting twice the cases with 5 consecutive 1's and 5 consecutive 0's: $$0000011111\qquad 1111100000$$ So we need to substract 2 (2 possible bit strings) for a total of: iphone syncing photos via finder

"WebIt 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.
