Program Description Answer

On an average analysis, the “sequential search” algorithm searches half of the array of “n” elements which means it leads to “n/2” comparisons.

Hence, the correct answer is option “A”.

AIM: Write a program to do Linear Search using a given Search Key in an un- sorted Linear Array 'A' which has N values in it. Description: The linear search compares each element of the array with the search key until the search key is found. To determine that a value is not in the array, the program must compare the search key to every element in the array 'A'. It is also called "Sequential Search" because it traverses the data sequentially to locate the element. Algorithm: (Linear Search) LINEAR SEARCH (A, N, SKEY) Here A is a Linear Array with N elements and SKEY is a given item of information to search. This algorithm finds the location of SKEY in A and if successful, it returns its location otherwise it returns -1 for unsuccessful. 1. Repeat step-2 for K = 0 to N-1 2. if(A [K] = SKEY) return K [Successful Search] [End of loop of step-1 ] 3. return -1 [Un-Successful] 4. End.
