In which scenarios would you prefer to use an array over a linked list, and vice versa?
Step by step
Solved in 3 steps
- 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.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()What are the advantages of a linked list over an array? In which scenarios do we use Linked List and when Array?
- What benefits does a linked list have over an array?Comparing a linked list to an array, what benefits do you see?Looking at all four list implementations, which actions/methods tend to be less efficient in the Linked List implementation compared to the Array Implementation? Explain why for each action/method you specify.
- Give example of ArrayListYou are working for GreatDataStructures Inc. You have to pick a data structure for a problem that requires accessing all the stored elements quickly as well as adding elements to and removing elements from the end of the list of elements. The number of elements in the list is not known. The best data structure to choose is a linked list with no tail reference a linked list with a tail reference a doubly-linked list an array list O an array stackWhat is the difference between a singly-linked list and a doubly-linked list? In what situation would you use a singly-linked list over a doubly-linked list? In what situation would you use a doubly-linked list over a singly-linked list?
- JavaScript Given a singly linked list of integers, determine whether or not it's a palindrome. // Singly-linked lists are already defined with this interface: // function ListNode(x) { // this.value = x; // this.next = null; // } // function isListPalindrome(head) { } Note: in examples below and tests preview linked lists are presented as arrays just for simplicity of visualization: in real data you will be given a head node l of the linked list Example For l = [0, 1, 0], the output should beisListPalindrome(l) = true; For l = [1, 2, 2, 3], the output should beisListPalindrome(l) = false.Arrays and linked lists both gather and store data, but what's the difference?What are the key differences between arrays and linked lists and how do they work?
