The following diagram given below tries to explain queue representation as data structure − As in stacks, a queue can also be implemented using Arrays, Linked-lists, Pointers and Structures. Sorting refers to the operation or technique of arranging and rearranging sets of data in some specific order. An Algorithm (a bunch of steps to complete a task) may perform these operations many times and if one of our Data Structure operations is inefficient, so is our algorithm. Introduction to Data Structures and Algorithms. Here a pointer stores the address of the first node or element of the list, and that element points to the next node and so on. An important point to note here is that you can do lots of things faster if you arrange the data differently. Data Structures is about rendering data elements in terms of some relationship, for better organization and storage. Non-Liner Data Structures Index − Each location of an element in an array has a numerical index, which is used to … For example, a phone number directory can be thought of as a list where each record has three fields - 'name' of the person, 'address' of that person, and their 'phone numbers'.
