Describe how linear search works with an example.
The search divides the list in half and checks the middle element first.
The search checks all elements in reverse order starting from the last element.
For example, in a list [3, 5, 2, 8, 1], to find the number 8, the search checks 3 (not a match), then 5 (not a match), then 2 (not a match), then 8 (match found). The search stops here.
The search uses a binary tree structure to find the number.
