WebCodes with this property are called prefix codes. For instance, the encoding of e as 0, a as 10, and t as 11 is a prefix code. A word can be recovered from the unique bit string that encodes its letters. For example, the string 10110 is the encoding of ate. To see this, note that the initial 1 does not represent a character, but 10 does ... WebFor the example above, the initial conditions are: a 0 = 0, a 1 = 3;and a 0 = 5, a ...

WebSome definitions: A bit is either 0 or 1 (bit is short for “binary digit”). Thus a bit string is a string of bits. The length of a bit string is the number of bits in the string; the weight of a bit string is the number of 1's in the string (or equivalently, the sum of the bits). A $n$-bit string means a bit string of length $n\text{.}$.

WebApr 9, 2013 · A bit string is just a string of $0$'s and $1$'s, often of a given length. You might wonder, for example, how many five bit strings have at least four $1$'s. You might wonder how many have a run of (exactly or at least) three $1$'s in a row. Both of these are small enough you can count by hand. You have to read the question carefully. $\endgroup$
