If you want to create a linkedlist, how many nodes should it have to be effective? How long does the longest one take?
*The Question In the Picture Criteria a. Create a class called Queue with member variable queueArr, integer queue array, integer rear, integer front b. i. Initialize rear and front to -1ii. Receive an integer and check if queue is full, if not then insert the integer to the queue arrayiii. Delete front element from queue if front is not equal to rear (empty)iv. Print out the queue array if rear is not equal to front. c. i. Provides a choice to the user if they want to insert, delete or display the queue. ii. According to the user response, the appropriate function is called.
If front=2 and rear=5, how many elements are there in an array-based queue (note: rear is pointing at the next free location) O 3 4 2 5
Student should be able to develop the programs for queue using arrays and linked list Exercise 1: Implementation of Queue using Array or Linked list Real life situation. Design a simulation that can help to answer it. Customers at a grocery store want to check-out The grocery have 3 counter and the costumer must choose one of the counter Counter 1:3 people assembly Counter 2: 2 people assembly Counter 3: 3 people assembly The costumer should choose the fastest way to check out
Node* temp=new node(); if(temp==0) return 0; return 1; we can use this to check if the linked queue is full or not Select one: True False
Below you're given a Node class and a LinkedList class. You will implement a method for the LinkedList class named "delete48in148". That is, whenever there is a sequence of nodes with values 1, 4, 8, we delete the 4 and 8. For exCample, Before: 1 -> 4 -> 8 LAfter: 1 Before: 7 -> 1 -> 4 -> 8 -> 9 -> 4 -> 8 After: 7 -> 1 -> 9 -> 4 -> 8 Before: 7 -> 1 -> 4 -> 8 -> 4 -> 8 -> 4 -> 8 -> 9 After: 7 -> 1 -> 9 Note from the above example that, after deleting one instance of 48, there may be new instances of 148 formed. You must delete ALL of them. Requirement: Your implementation must be ITERATIVE (i.e., using a loop). You must NOT use recursion. Recursive solutions will NOT be given marks. import ... # No other import is allowed

Given the doubly linked list: head tail 10 20 30 60 40 50 assuming that the Node class has three fields: prev, info, and link, what will be the list after performing the following operations?
