- Question : Write a program to remove duplicates from a doubly linked list. e.g (1,2,3,4,5,2) (you will remove the 2nd duplicate) and then swap two data items in a doubly linked list. swap address of node 2 with node 4.Use Java : Delete N Nodes After M Nodes of a Linked List You are given the head of a linked list and two integers m and n.Traverse the linked list and remove some nodes in the following way:- Start with the head as the current node.- Keep the first m nodes starting with the current node.- Remove the next n nodes- Keep repeating steps 2 and 3 until you reach the end of the list.Return the head of the modified list after removing the mentioned nodesWhich of the following statement is not true about the doubly linked list? A. We can traverse in both the directions. B. It requires extra space C. Implementation of doubly linked list is easier than the singly linked list D. It stores the addresses of the next and the previous node
- python programming Write a function that will insert a new value into the middle of a Linked List. INPUT: The head of the Linked List, the value to insert OUTPUT: Nothing is output RETURNED: Nothing is returnedComplete the below code so the program will : - Receive a word from user - Then, transfers it into a doubly linked list (for example if the word is Hello, then the doubly linked list would have 5. nodes: H, e, l , l , o) - Finally, uses insertion-sort to scramble it into descending order. - Example: If the word is "Hello", the output should look like below: - List after insertion sort: o l l h e Some of the code has been written below in main.py class Node:def __init__(self, data):self.data = dataself.next = Noneself.prev = None# Empty Doubly Linked Listclass DoublyLinkedList:def __init__(self):self.head = None# Inserts a new node on the front of listdef append(self, new_data): if self.head is None:self.head = new_dataself.tail = new_dataelse:self.tail.next = new_datanew_data.prev = self.tailself.tail = new_datadef printList(self):if(self.head is None):print('Empty!')else:node = self.headwhile(node is not None):print(node.data),node = node.next print()def remove(self,…Write the following function that sorts and merges two lists into a new sorted list. The new list contains only even numbers. def myMergeEvenList(list1, list2): Enter list1: 10,5,6,7 Enter list2: 12,8,5,0,1 The merged list is: 0,6,8,10,12
- Considering all the elements and its indexes at the right side:Write a sequence of List operations that would result to a LIST that contains ONLY the elements with its respective indexes: {index[00]=104, index[01]=165, index[02]=115, index[03]=384, index[04]=248, index[05]=117}.TRUE or FALSE? Answer the following question and state the reason why: The delete operation only involves the removing of the node from the list without breaking the links created by the next node. You need an array to represent each node in a linked list. STL lists are also efficient at adding elements at their back because they have a built-in pointer to the last element in the list. A circular linked list has 2 node pointers. cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null. In a dynamic stack, the node that was popped is deleted. In a dynamic stack, the pointer top stays at the head after push operation. STL function top returns a reference to element at the top of the…C++ question 1.) Write an iterative routine that will take a string, go through each character of the string and enqueue the character if it is a punctuation (.,?!), else toss the character. When end of string is reached, then dequeue the characters, count how many punctuations are there, then print the count. 2.) Write a routine that would receive a pointer to the top of the linked list that has an integer for each node. Change all odd integers to even by adding one. But count the numbers you changed and print the count.
- Arrays and linked lists both gather and store data, but what's the difference?Answer the given question with a proper explanation and step-by-step solution. Write in Java: Write a menu-driven program to illustrate the use of a linked list. The entries will only consist of integer number keys (values). The program should implement the following options in order: • Insert- insert a key into a list- not allowing duplicate integers. • Delete- delete a key from the list. • Search- finds or does not find a particular key in the list. • Print- prints the list graphically in horizontal form. If the list is empty output- "Nothing to print". • Size- count of all the keys in the list. • Sort- sorts the keys in the list in ascending order. • Reverse- reverses the order of the keys in the list • Rotate- moves the key at the front of the list to the end of the list. If the list has 0 or 1 elements it should have no effect on the list. • Shift- rearranges the keys of a list by moving to the end of the list all values that are in odd number positions (indexes) and otherwise…(c++)write a program to insert node at specified number in single linked list? (c++)write a program to insert node at specified number in double linked list?
