Useful for home works. In addition, you have been given an element M you need to find and print the index of the last occurrence of this element M in the array if it exists in it, otherwise print -1. In Linear search the search goes sequentially and check one by one.After chcek all item if a match found then it returned otherwise the search continue till the end. Linear search is a way of finding a target value within a collection of data. If it's present, then at what location it occurs. It sequentially checks each element of the collection data for the target value until a match is found or until all the elements have been searched.
