- 3 Counting k-inversions A k-inversion in a bitstring b is when a 1 in the bitstring appears k indices before a 0; that is, when b; = 1 and bi+k = 0, for some i. For example, the string 010010 has two 1-inversions (starting at the second and fifth bits), one 2-inversion (starting at the second bit), and one 4-inversion (starting at the second bit). Devise an algorithm which, given a bitstring b of length n, counts all the k-inversions, for each k from 1 to n - 1. Your algorithm should run faster than (n²) time. You can assume arithmetic on real numbers can be done in constant time. Give a 3-part solution.arrow_forwardCryptography and cryptanalysisarrow_forwardFill in the empty spaces in the following table. As you do, please be aware of the following: • All numbers are considered unsigned (positive) for this table • All binary answers must have 16 bits • You need to put a space after every 4 bits for binary values. • All hex values must use capital letters Unsigned Decimal 16-bit Binary Нех 7E 0000 0010 1010 1100 965arrow_forward
