NettetIn this tutorial, we are going to learn about linear search and binary search in Python. It’ll help us to justify where should we use binary search and where linear search. So we are willing to do this in python and to do this we need matplotlib. Installation of matplotlib In the linear search algorithm, we start from the index 0 of a list and check if the element is present at the index or not. If the element is present at the index, we return the index as output. Otherwise, we move to the next index until we find the element that is being searched or we reach the end of the list. For … Se mer The algorithm for linear search can be specified as follows. Input to algorithm:A list and an element to be searched. Output:Index of the element if the element is present. Otherwise,-1. 1. Start from index 0 of the list. 2. … Se mer A linear search algorithm is very costly in terms of time complexity. It has O(n) complexity in the worst case where n is the number of elements in the list. Another drawback is that it … Se mer In this article, we have discussed the linear search algorithm.
