WebDefinition: Linear search or sequential search is a method for finding a particular value in a list that consists of checking every one of its elements, one at a time and in sequence, until the desired one is found. Linear search is the simplest search algorithm; it is a special case of brute-force search. WebHash table operations are typically considered to be O(1). This is a bit of lie because it depends on the number of collisions you get. But its close to O(1) and definitely better …
