Problem Statement The problem “Implementation of Deque using Doubly Linked List” states that you need to implement the following functions of Deque or Doubly Ended Queue using a doubly linked list, insertFront(x) : Add element x at the starting of Deque insertEnd(x) : Add element x at the end of …
What is Page Replacement? The modern operating systems use paging for memory management and many times there is a need for page replacement. Page replacement is the process of replacing a page that is currently present in the memory with a page that is needed but is not present in …
Problem Statement Write an algorithm to perform searching and insertion in Binary Search Tree. So what we are going to do is insert some of the elements from input into a binary search tree. Whenever asked to search a particular element, we’ll be searching it among the elements in BST(short …
The most commonly used operations on any data structure are insertion, deletion, and searching. Hash Table is able to perform these three operations with the average time complexity of O(1), while self-balancing Binary Search Trees take O(log n) time complexity. At first, it seems as Hash Tables are better than …
Listening to Data Structure Designing, A lot of people might want to run away looking at the title itself. Those who know me know that I am not leaving until I explain the concept entirely. Embark with me on a journey to learn a problem and a few ideas on …
Before getting on and along with what is the sliding window technique? What it does and how it does what it does let us get the hang of this concept by a small problem Given an array of integers, we have the task of finding the minimum sum from all …
This model was developed in 1983 by the International Standards Organization (ISO). This was the first step taken to standardized the international protocols used in various layers. As it deals with connecting open systems, that is, systems that are open for communication with other systems, the model is called the …
A priority queue is a type of data structure which is similar to a regular queue but has a priority associated with each of its element. Higher the priority earlier the element will be served. In some cases, there are two elements with the same priority then, the element enqueued …
What is Recursion? Recursion is simply defined as a function calling itself. It uses its previously solved sub-problems to compute a bigger problem. It is one of the most important and tricky concepts in programming but we can understand it easily if we try to relate recursion with some real …
A binary search tree is a Binary tree with some rules that allows us to maintain the data in a sorted fashion. As it is a binary tree hence, a node can have at max 2 children. Structure of a Binary Search Tree node Rules for Binary tree to …
