Explanation: It is practical to implement linear search in the situations mentioned in When the list has only a few elements and When performing a single search in an unordered list, but for larger elements the complexity becomes larger and it makes sense to sort the list and employ binary search or hashing.

How are linear search used in real life?

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.

Where is linear searching used in data structure?

Linear search is mostly used to search an unordered list in which the items are not sorted. The algorithm of linear search is given as follows.
