Question

Define linear searching, algorithm and complexity in data structure

Answer 1

In computer science, linear search or sequential search is a method for finding a target value within a list. It sequentially checks each element of the list for the target value until a match is found or until all the elements have been searched.[1]

Linear search runs in at worst linear time and makes at most n comparisons, where n is the length of the list. If each element is equally likely to be searched, then linear search has an average case of

comparisons, but the average case can be affected if the search probabilities for each element vary. Linear search is rarely practical because other search algorithms and schemes, such as the binary search algorithm and hash tables, allow significantly faster searching for all but short lists.[2]

Answer 2

In computer science, linear search is a method of finding a target value within a list, it sequentially check each element of the list for the target value until a match is found.
Algorithm is a set of rules to be filled in calculations or other problem solving operations especially by computer.
