A header linked list is a type of linked list that has a header node at the beginning of the list. In a header linked list, HEAD points to the header node instead of the first node of the list. The header node does not represent an item in the linked list. This data part […]

A doubly linked list or two way linked list is a type of linked list that contains a pointer to the next node as well as the previous node in the sequence. That is, each node in a doubly-linked list consists of: data – Data Item. prev – Address of previous node. next – Address

A circular linked list is a type of linked list in which the last node is also connected to the first node to form a circle. Thus a circular linked list has no end. There are two types of linked lists: Circular Singly Linked List. Circular Doubly Linked List. Representation of Circular Linked List Each

A singly linked list is the most simple type of linked list, with each node containing some data as well as a pointer to the next node. That is a singly linked list allows traversal of data only in one way. There are several linked list operations that allow us to perform different tasks. The

Linked list is a linear collection of data elements called nodes. It can be considered as a series of nodes, with each node storing data as well as the address of the next node. Linked lists contain a pointer variable HEAD that stores the address of the first node. Also, we store NULL in the

A matrix is a two-dimensional array made of m rows and n columns, and so m x n elements. A matrix is called a sparse matrix if most of its elements are 0. An example of a sparse matrix of order 3 x 4 is shown below. It is worth noting that matrix A of

A parallel array is a structure of an array. It contains multiple arrays of the same size, in which the i-th element of each array is related to each other. All the elements in a parallel array represent a common object or entity. In the example below, we store the name and age of five

In c programming, multidimensional arrays can be simply defined as arrays of arrays. Multidimensional arrays store data in tabular form. Declaring Multidimensional Arrays in C The declaration of an n-dimensional array takes the following form, For example, Here A is a 2-dimensional array with 3 rows and 5 columns. The total number of elements that

Inserting or deleting an element at the of an array can be easily done. If we need to insert or remove an element in the middle of an array, half of the items must be shifted to accommodate the new element while maintaining the order of the other elements. Inserting a new element in an
