You are given a sorted array A of n integers. The length of the array is n but you
are not given the value of n; an attempt to access element A[i] with i > n returns the error message \infty .
Give an algorithm that takes an integer x as input and finds a position in the array containing x, if such a position exists, in O(log n) time.
