To find the solution to the problem we would take the following steps:

Nettet27. mar. 2024 · Drawbacks of Linear Search: Linear search has a time complexity of O(n), which in turn makes it slow for large datasets. Not suitable for large arrays. Linear search can be less efficient than other … 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.
