How many minimum number of comparisons are required to search an element from 'n' elements in Linear Search?

Question

Choose the statements that are correct.
Options:
(A) For Binary Search, all the elements have to be sorted.
(B) For Linear Search, all the elements have to be sorted.
(C) Linear Search takes less time for searching in worst case than binary search’s worst case.
(D) Linear Search always gives fast result whether elements are sorted or not.
Choose the correct answer from the options given below:

Answer 1

To establish the fewest comparisons needed for Linear Search, we examine its operation. Linear Search sequentially checks every list item from the start until the target is found or the list concludes.

The optimal scenario occurs when the target is the list's initial element. Here, a single comparison suffices. Consequently, the minimum comparison count is: 1

The process for achieving this minimum in Linear Search involves:

Comparing the target element to the list's first element.
If they match, the search concludes.

This demonstrates that the best-case for Linear Search necessitates only one comparison, affirming the correct result: 1.
