Search algorithms are useful in many areas. One such search algorithm is Linear search. In this piece, you are going to get the complete details about Linear search algorithm in Java.
There are mainly two types of search algorithms including those that don’t make any assumption regarding the order of the list and another one that assumes the list is ordered. Linear search is the simplest search algorithm among them.
Linear search is implemented when you want to find an element in a list. It performs a sequential search on each element of a list till a match is not found or the search of the entire list is done. The return value is considered as the index at which the search term was found or indicator when the search term was not found.
If you have looked closely, then you will find that the number of comparisons is proportional to the number of items in the array, N in both the worst and average case, the. Therefore, we can say that the number of comparisons is order N in both or O(N) for short. For the best case, the number of comparisons is order 1, or O(1) in short.
So, isn’t it is easy to use the Linear search algorithm. Anyone can learn it with some practice if he knows to program in any language.
