Data Structure Questions Asked in Interview

struct node { int data; struct node *next; }; struct node *head, *ptr; ptr = (struct node *)malloc(sizeof(struct node)); To create a node in a singly linked list in C, you would typically define a structure representing the node, like this: cCopy code struct Node { int data; struct Node* next; }; Then, you can … Read more

The size of a linked list can be incremented at runtime which is impossible in the case of the array. The List is not required to be contiguously present in the main memory, if the contiguous space is not available, the nodes can be stored anywhere in the memory connected through the links. The List … Read more

A linked list is considered both linear and non-linear data structure depending upon the situation. On the basis of data storage, it is considered as a non-linear data structure. On the basis of the access strategy, it is considered as a linear data-structure. Linked lists are considered linear data structures. In a linked list, each … Read more

Linked List is the collection of randomly stored data objects called nodes. In Linked List, each node is linked to its adjacent node through a pointer. A node contains two fields, i.e. Data Field and Link Field. A linked list is a fundamental data structure used in computer science for storing and organizing data. It … Read more

Row-Major Order: If array is declared as a[m][n] where m is the number of rows while n is the number of columns, then address of an element a[i][j] of the array stored in row major order is calculated as, Address(a[i][j]) = B. A. + (i * n + j) * size Column-Major Order: If array … Read more
