Which is the best case for linear search?
In linear search, best-case complexity is O(1) where the element is found at the first index. Worst-case complexity is O(n) where the element is found at the last index or element is not present in the array. In binary search, best-case complexity is O(1) where the element is found at the middle index.
How can sequential search be improved?
In summary, a sequential search is improved by ordering the list only in the case where we do not find the item.

10 Optimizations on Linear Search
- Don’t optimize code that is fast enough.
- Use SIMD instructions.
- Work in parallel.
- Hide calculation in another function.
- Maintain the max along the way.
- Hide long calculations from users.
- Use a “good enough” value instead.
- Seek inspiration from the upstream processes.
Is sequential and linear search the same?
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.
What is the best case of sequential search?
The best case for sequential search is that it does one comparison, and matches X right away. In the worst case, sequential search does n comparisons, and either matches the last item in the list or doesn’t match anything.
In what situation sequential search is good?
The sequential search is used whenever the list is not ordered. Generally, you use this technique only for small lists or lists that are not searched often.
Where is sequential search used?
The sequential search is used whenever the list is not ordered. Generally, you use this technique only for small lists or lists that are not searched often. In the sequential search, we start searching for the target at the beginning of the list and continue until we find the target.
