The problem of finding the nth node from the end of a linked list involves finding the node that is n positions away from the end of the linked list. For example, if the linked list has 10 nodes and n is 3, we need to find the 3rd node from the end of the […]

A palindrome is a sequence of characters that is read the same forward and backward. For example, “racecar” is a palindrome. In the context of a linked list, we can consider it a palindrome if the sequence of values in the list is the same when read from left to right and from right to […]

A linked list is a data structure in which each element in the list, known as a node, contains a value and a reference to the next node in the list. Here’s an example of a linked list: In this list, each node contains a value and a reference to the next node in the […]

Data structures are an essential part of computer science, and they play a critical role in designing efficient algorithms. Two of the most commonly used data structures are arrays and linked lists. While both of these data structures are used to store and manipulate collections of data, they differ in their implementation and functionality. In […]

Ruby has a built-in linked list class called LinkedList, which is part of the enumerator package. The LinkedList class is a linear data structure that consists of a sequence of nodes, where each node contains a data element and a reference to the next node in the list. Here is an example code to create […]

Given a sorted linked list, write a function to remove all the duplicate elements from the list, such that each element appears only once. Example: Input: 1 -> 1 -> 2 Output: 1 -> 2… Read More

In Ruby, a linked list is a data structure that consists of a sequence of nodes. Each node in the list contains a data element and a reference (or pointer) to the next node in the sequence. The first node is called the head of the list, and the last node is called the tail […]
Read MoreSkip lists are a probabilistic data structure that uses multiple levels of linked lists to provide efficient search and insertion operations. Each node in a skip list has multiple forward pointers, allowing for efficient traversal of nodes that are farther away from the current node. Skip lists are designed to improve the efficiency of search […]

Linked lists are commonly used data structures in computer programming. Linked lists consist of nodes that are dynamically allocated, meaning that memory must be manually managed. Memory management can be a complex and error-prone task, and to make it easier, shared pointers are used in linked list implementation. Shared pointers are smart pointers that help […]
