|
Data does not need to be in order.
|
|
Performs well over large ordered lists.
|
|
Can only work on an ordered list. If unordered must use a linear search.
|
|
Slow with large data sets.

Detailed explanation-1: -The linear search starts searching from the first element and compares each element with a searched element till the element is not found. It finds the position of the searched element by finding the middle element of the array. In a linear search, the elements don’t need to be arranged in sorted order.
Detailed explanation-2: -Advantages of a linear search With today’s powerful computers, small to medium arrays can be searched relatively quickly. The list does not need to sorted. Unlike a binary search, linear searching does not require an ordered list. Not affected by insertions and deletions.
Detailed explanation-3: -Best Answer Linear search needs greater time complexities compared to other searching algorithms, so it consumes more time. So, it is a disadvantage of this linear search.
Detailed explanation-4: -Linear Search is defined as a sequential search algorithm that starts at one end and goes through each element of a list until the desired element is found, otherwise the search continues till the end of the data set. It is the easiest searching algorithm.
Detailed explanation-5: -Linear search can be suitable for searching over an unsorted array. whereas, Elements in the array need to be in sorted order for binary search. The binary search algorithm uses the divide-and-conquer approach, it does not scan every element in the list. Hence, It is the best search algorithm.
