MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -One of the most straightforward and elementary searches is the sequential search, also known as a linear search. As a real world example, pickup the nearest phonebook and open it to the first page of names. We’re looking to find the first “Smith". Look at the first name.

Detailed explanation-2: -Linear Search best case For a list that contains n items, the best case for a linear search is when the target value is equal to the first element of the list. In such cases, only one comparison is needed. Therefore, the best case performance is O(1).

Detailed explanation-3: -Linear Search Best and Worst Cases The best-case performance for the Linear Search algorithm is when the search item appears at the beginning of the list and is O(1). The worst-case performance is when the search item appears at the end of the list or not at all.

Detailed explanation-4: -Linear search can be applied to both single-dimensional and multi-dimensional arrays. Linear search is easy to implement and effective when the array contains only a few elements. Linear Search is also efficient when the search is performed to fetch a single search in an unordered-List.
