Suppose we have a circular linked list of numbers, implemented as a pair of arrays, one storing the actual numbers and the other storing successor pointers. Specifically, let X[1.n] be an array of n distinct real numbers, and let N[1..n] be an array of indices with the following property: If X is the largest element of X, then X[N] is the smallest element of X ; otherwise, X[N] is the smallest element of Xthat is larger than X[i]. For example: 123 4 56 789 X[i83 54 1631 45 99 78 62 27 Ni6 89 5 2 3 1 74 Describe and analyze a randomized algorithm that determines whether a given number x appears in the array X in O(Vn) expected time. Your algorithm may not modify the arrays X and N.
