The importance of sorting lies in the fact that data searching can be optimized to a very high level, if. Sorting arranges data in a sequence which makes searching easier. A sorting algorithm is an algorithm made up of a series of instructions that takes an array as input, performs specified operations on the array, sometimes called a list, and outputs a sorted array. Sorts random shuffles of integers, with both speed and the number of items adapted to each algorithms complexity. Various types and forms of sorting methods have been explored in this tutorial. In a linear search, each element of the array is checked until a match is found. The best way to choose the right sorting method for you needs is to test each method again various types of inputs. In particular, against a sample of the kind of data you intend to sort. Because searching and sorting are common computer tasks, we have wellknown algorithms, or recipes, for doing searching.
