3- Assume that we have a single linked list (sll) as follows: SingleLinkedList sll = new SingleLinkedList (); sl1.add (4); sll.add ('D'); sl1.add (1): sll.add ('E'); sl1.add (6); sll.add ('R'); sl1.add (3): sll.add ('Y'); sll.add (2); sll.add ('A'); The single linked list includes a pair of values representing the letter followed by the count of this letter. Write a procedure in the Single Linked List class that decodes and prints the text in the list. At the end of the program, the list must remain the same. public class Singlelinked List { private Node head; public void add(Object dataToAdd) {.} public void display() {.. } public int size() { .} // write your method here } Notes: - You must use ONLY single linked list data structure. Don't use other different data structures like string, normal (pure) array, stack, queue, array list, or DLL. Example: head 4 |-> D ->E |->6 |->3 |->Y 2 Output: DDDDERRRRRRYYYAA

1. Assume you have a queue with operations: enqueue(), dequeue(), isEmpty(). How would you use the queue methods to simulate a stack, in particular, push() and pop() ? Hint: use two queues, one of which is the main one and one is temporary.
B: Draw the state of the queue (with size 4) after the following sequence of Enque and Deque operations : Deque size() Enque(2); Enque(3); Enque (1); Deque; Enque(4); Deque(); Enque(5); peek() Deque() Deque(); data structure in java
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
The essential condition which is checked before deletion in a linked queue is? a) Underflow b) Overflow c) Front value d) Rear value

Problem 7: Assume that a queue class called XQueue has a no argument constructor, an enqueue() method, a dequeue() method and an isEmpty() method. Write a method that merges two given queues by copying the elements in an alternating sequence and returning the resulting combined queue. Note: make sure that you don't include unnecessary spaces in your answer! public XQueue merge(XQueue q1, XQueue q2) { XQueue neWQueue = new XQueue(); while (!q1.isEmpty() && !q2.isEmpty()) { newQueue.enqueue( #01 ); newQueue.enqueue( #02); } while (!q1.isEmpty()) { #03 ; } while (!q2.is Empty()) { #04 ; } return newQueue (); }
