What is the initial step in executing a binary search on a sorted array?*1 pointA. Traverse the entire array from start to end.B. Compare the target value to the middle element.C. Sort the array in ascending order.D. Calculate the average value of the elements.

Suppose there are 11 items in sorted order in an array. How many searches are required on average, if binary search is employed and all searches are successful in finding the item?

If an element is present multiple times in an array, what will a linear search return?The index of the last occurrence of the elementThe index of the first occurrence of the elementThe number of occurrences of the elementThe index of a random occurrence of the element

Q3(b) Consider the following algorithm for searching for a given number x in an unsorted array A[1..n] having n distinct values. 1. Choose an i uniformly at random from 1..n 2. if A[i]=x then stop else goto 1 Assuming that x is present in A, what is expected number of comparisons made by algorithm before it terminates
