I have published code that shows examples of the Linear Search Algorithm.

The linear search algorithm iterates through each item in our data structure in search for a specific value. If the current item matches, we can return, else we must continue to the next item.

In the worse case, this requires that we search through all items because in a unsorted structure, we cannot say whether an untesetd value is the value we are searching for.
