What are some examples of linear search algorithms?

Linear search is a simple algorithm that checks each element in a list until it finds the target. For example, if you have a list of numbers and you want to find the number 5, the algorithm will start from the first element and check each one until it finds 5.

Can you give me a specific example with numbers?

Sure! Let's say we have the list [3, 7, 1, 5, 9]. If we want to find the number 5, the linear search will check 3, then 7, then 1, and finally it will find 5 at index 3.

What is the time complexity of linear search?

The time complexity of linear search is O(n), where n is the number of elements in the list. In the worst case, it checks every element.

Are there any situations where linear search is preferred?

Yes, linear search is preferred for small or unsorted lists where the overhead of more complex algorithms isn't justified.
