WebAug 4, 2024 · A linear search is the most simple search algorithm. Each data item is searched in order from the first value to the last as if they were all laid out in a line. The list does not have to be in any order before it is searched. This search is also known as a sequential search because the list is searched in a sequence from start to end. WebLinear Search and Binary Search are the two popular searching techniques. Here we will discuss the Binary Search Algorithm. Binary search is the search technique that works efficiently on sorted lists. Hence, to search an element into some list using the binary search technique, we must ensure that the list is sorted. durational shortage area permitWebBinary Search A binary search is a way of looking for a piece of data in an ordered list by continually splitting the list in half.
