Step by step
Solved in 3 steps
- If an array of size 6 is used to implement a circular queue, and the current values of rear and front are O and 3 respectively, when one element is removed from the queue and two more elements are added, what are the values of rear and front, respectively? O 1, 5 O 4, 2 5, 1 O 2, 3 None of the aboveAssume class MyStack implements the following StackGen interface. For this question, make no assumptions about the implementation of MyStack except that the following interface methods are implemented and work as documented. Write a public instance method for MyStack, called interchange(T element) to replace the bottom "two" items in the stack with element. If there are fewer than two items on the stack, upon return the stack should contain exactly two items that are element.The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
- QUESTION 9 Write a complete Java program to implement a QUEUE in a bank using LinkedList class as follows: • Provide the menu as shown below; use an infinite loop; stop when user opts 4. 1. Add a customer 2. Remove a customer 3. Show the queue 4. Exit • Add a customer should add an int number at the end of queue using the method addLast(). • Remove a customer should delete the int from front using the method removeFirst(). Show the queue should display the numbers in queue using the method System.out.printIn(). For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).In Java and C++ create a Generic ArrayList where all elements in the ArrayList must be of the same type. In every node of the linked list the size of the array it contains must be at least double the size of the previous node’s array. Between O(1) time and O(n) time. add(int index, E e) clear() contains(E e) ensureCapacity(int minCapacity) isEmpty() get(int index) remove(int index) size()Write a method moveUp for the ArrayBoundedStack class. The method has a parm named item (type T). moveUp finds the first occurrence of item (the occurrence closest to the top of the ti ww stack) and moves it to the top. Throw NoSuchElementException if item is not in the stack. DO NOT USE ANY METHODS OF THE STACK CLASS. For example, here is the before and after if item is "blue". "red" "blue" "green" "red" before: "purple" after: "green" "purple" "yellow" "blue" "yellow" "blue" "blue"
- Please Use Java language Write a method “mergeQueueStack” that takes a queue as a parameter of type: Queue of integers and a stack as a second parameter of type: Deque of integers Remove all the items from the queue and remove all the items from the stack then add them to a LinkedList by alternating between an item from queue then an item from stack. Don’t assume initially both the queue and the stack have the same number of items. The method should return the linked list of type integers. Example: If queue has : 1,2,3,4,5 and stack has 10, 20, 30 (where 10 is at top of the stack) then the linkedList should contain: 1,10,2,20,3,30,4,5Student 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 outBreak out the restrictions placed on the stack and its unrestricted counterpart.
- Discover the stack's true potential by letting it shine.IN JAVA This triple-ended queue exercise can be found at https://open.kattis.com/problems/teque. The requirements for this program are compatible with those of the Kattis problem, so a solution should produce correct results when submitted on Kattis. The Triple-Ended QUEue supports four operations: push_back x: inserts the element x at the end of the TEQUE push_front x: inserts the element x at the front of the TEQUE push_middle x: inserts the element x so that the insertion index for x is (k + 1)/2 for a 0-based indexed TEQUE. get i: prints out the ith index element (0-based) of the TEQUE. The TEQUE will be implemented as a linked list. The usual implementation requirements apply along with a screenshot of the results from Kattis. Sample input 10 push_back 1 push_front 2 push_back 3 push_front 4 push_middle 5 push_back 6 get 3 push_middle 7 push_middle 8 get 5 Sample Output 1 1 Subject: Java ProgrammingA skip listThe second programming homework is already on a server (http://marmoset.famnit.upr.si).In this task, a skip list data structure should be implemented. You can follow the followinginstructions:- Implement the class NodeSkipList with two components, namely key node and arrayof successors. You can also add a constructor, but you do not need to add anymethod.- In the class SkipList implement a constructor SkipList(long maxNodes). The parameter maxNodes determines the maximal number of nodes that can be added to askip list. Using this parameter we can determine the maximal height of a node, thatis, the maximal length of the array of successors. As the maximal height of a nodeit is usually taken the logarithm of the parameter. Further, it is useful to constructboth sentinels of maximal height.- In the class SkipList it is useful to write a method which simulates coin flip andreturns the number of all tosses until the first head comes up. This number representsthe height of a node…
