"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 \(n\text{.}\). We will write \(\B^n_k\) to mean the set of … " - Bit strings discrete math examples
