This implementation uses a singly linked list to represent the queue. The Queue class has two private fields: head points to the first node in the list (which is the front of the queue), and tail points to the last node in the list (which is the back of the queue). It also has a … Read more
A stack is a data structure that follows the Last-In-First-Out (LIFO) principle. In other words, the most recently added item to the stack is the first item to be removed. A stack has two primary operations: push, which adds an item to the top of the stack, and pop, which removes and returns the top … Read more
A Singly Linked List is a specialized case of a generic linked list. In a singly linked list, each node links to only the next node in the sequence, i.e if we start traversing from the first node of the list, we can only move in one direction. The Node class represents a node in the … Read more
A polynomial is an algebraic expression consisting of one or more terms, where each term consists of a variable raised to a non-negative integer power multiplied by a numerical coefficient. Polynomials are widely used in mathematics and science to represent a wide range of functions, from simple curves to complex shapes. To add two polynomials, … Read more
To remove duplicate elements from a sorted linked list, we can traverse the linked list and compare each node’s data with the data of the next node. If the data is the same, we can remove the next node by setting the current node’s next pointer to the next node’s next pointer. class Node(var data: … Read more
To reverse a linked list, you can use the following approach: Node class represents a node in the linked list, with an integer data and a next reference to the next node in the list. reverseLinkedList function takes a head parameter, which is a reference to the head node of a linked list. The function … Read more
To check if a linked list is a palindrome, you can use the following approach: Firstly import Stack in program. it will be used to store the data of linked list. Node class represents a node in the linked list, with an integer data and a next reference to the next node in the list. … Read more
To find the middle element of a linked list, you can use the slow and fast pointer approach. Here are the steps: Node class represents a node in the linked list, with an integer data and a next reference to the next node in the list. The findMiddleElement function takes a head parameter, which is … Read more
To detect a loop in a linked list, you can use the Floyd’s cycle-finding algorithm, also known as the “tortoise and hare” algorithm. This algorithm works by using two pointers – a slow pointer and a fast pointer. The slow pointer moves one step at a time, while the fast pointer moves two steps at … Read more
A loop in a linked list is a situation where a node in the list points to a previous node, causing the list to have a cycle. In other words, a loop occurs when there is at least one node in the list that can be reached by following a chain of next pointers starting … Read more
