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 …
Problem Statement The problem “Implement Stack and Queue using Deque” states to write an algorithm to implement Stack and Queue using a Deque(Doubly Ended Queue). Example (Stack) Push(1) Push(2) Push(3) Pop() isEmpty() Pop() Size() 3 false 2 1 Example (Queue) Enqueue(1) Enqueue(2) Enqueue(3) Dequeue isEmpty() Size() Dequeue() 1 false 2 …
In Sliding Window Maximum problem we have given an array nums, for each contiguous window of size k, find the maximum element in the window. Example Input nums[] = {1,3,-1,-3,5,3,6,7} k = 3 Output {3,3,5,5,6,7} Explanation Naive Approach for Sliding Window Maximum For every contiguous window of size k, traverse …
