5. The following function indexCounter aims to find and return all the indices of the element x in a list L. if x is not in the list L, return an empty list. However, the implementation has a flaw, so that many times it will return error message. Can you fix the flaw? def indexCounter(L, x): indexList [] startIndex = 0 while startIndex < len(L): indexList.append (L.index (x, startIndex)) startIndex = L.index (x, startIndex) + 1 return indexList

Implement a LinkedList class that stores integers using dynamic memory and a proper main program to test it. The following member functions need to be properly implemented and tested: 1. Default constructor. 2. Parmetrized Constructor. 3. Sum. 4. Average. 5. InsertAtHead. 6. InsertAtTail. 7. Delete. 8. Pop. 9. Circular. 10. Display. Sample answer is also provided.
Instruction: To test the Linked List class, create a new Java class with the main method, generate Linked List using Integer and check whether all methods do what they’re supposed to do. A sample Java class with main method is provided below including output generated. If you encounter errors, note them and try to correct the codes. Post the changes in your code, if any. Additional Instruction: Linked List is a part of the Collection framework present in java.util package, however, to be able to check the complexity of Linked List operations, we can recode the data structure based on Java Documentation https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html package com.linkedlist; public class linkedListTester { public static void main(String[] args) { ListI<Integer> list = new LinkedList<Integer>(); int n=10; for(int i=0;i<n;i++) { list.addFirst(i); } for(int…

Make a doubly linked list and apply all the insertion, deletion and search cases. The node willhave an int variable in the data part. Your LinkedList will have a head and a tail pointer.Your LinkedList class must have the following functions: 1) insert a node1. void insertNodeAtBeginning(int data);2. void insertNodeInMiddle(int key, int data); //will search for keyand insert node after the node where a node’s data==key3. void insertNodeAtEnd(int data);2) delete a node1. bool deleteFirstNode(); //will delete the first node of the LL2. bool deleteNode(int key); //search for the node where its data==keyand delete that particular node3. bool deleteLastNode(); //will delete the last node of the LL3) Search a node1. Node* searchNodeRef(int key); //will search for the key in the datapart of the node2. bool searchNode(int key); The program must be completely generic, especially for deleting/inserting the middle nodes. Implement all the functions from the ABOVE STATEMENTS and make a login and…
Write a function in C++ that takes a pointer to an array as one parameter, and the length of the array as the second parameter. The function shall calculate the longest contiguous streak of odd numbers present in the array. You do not need to handle negative length arrays. Use Example: int. main(){ int array[] = {1,2,3,4,5,7,9}; std::cout << "Number Odd: << numOdd(array, 7); std::cout << std::endl; } Output: 3
Python’s list method sort includes the keyword argument reverse, whose defaultvalue is False. The programmer can override this value to sort a list in descendingorder. Modify the selectionSort function so that it allowsthe programmer to supply this additional argument to redirect the sort. selectionSort function: def selectionSort(lyst, profiler):i = 0 while i < len(lyst) - 1:minIndex = ij = i + 1 while j < len(lyst):profiler.comparison() # Countif lyst[j] < lyst[minIndex]:minIndex = jj += 1 if minIndex != i:swap(lyst, minIndex, i, profiler)i += 1 def swap(lyst, i, j, profiler):"""Exchanges the elements at positions i and j."""profiler.exchange() # Counttemp = lyst[i]lyst[i] = lyst[j]lyst[j] = temp Use this template in Python to modify the function above: def selection_sort(input_list, reverse):sorted_list = []#TODO: Your work here# Return sorted_listreturn sorted_listif __name__ == "__main__":my_list = [1, 2, 3, 4, 5]print(selection_sort(my_list, True)) # Correct Output: [5,…
Java programming In the Java programming language, write a method that lists all the elements of the list in reverseorder!
Write a Python code using the given function and conditions. Do not use Numpy. Use LinkedList Manipulation. Given function: def insert(self, newElement, index) Pre-condition: The list is not empty. Post-condition: This method inserts newElement at the given index of the list. If an element with the same key as newElement value already exists in the list, then it concludes the key already exists and does not insert the key. [You must also check the validity of the index].
In C++ I need to write a recursive function insertEnd that will call a recursive method insertEnd(const ItemType& newEntry, Node<ItemType>* node), to insert newEntry at the end of the linked list I completely stuck and can't figure out where the error is coming from. main #include <iostream> #include "LinkedList.cpp" int main() { Node<int>* first = new Node(1); Node<int>* second = new Node(2); Node<int>* third = new Node(3); first->next = second; second->next = third; cout<<first->data<<endl; cout<<first->next->data<<endl; cout<<first->next->next->data<<endl; LinkedList<int> list; //an empty linked list for(int i =0; i<10; i++){ list.inserEnd(i); list.display(); } return 0; } linkedlist.cpp #include "LinkedList.h" #include "iostream" using namespace std; template <class T> LinkedList<T>::LinkedList(){ head = nullptr; } template <class…
Problem2. Write a program that will remove an elements to an ArrayList/LinkList. Filename: ArrListRem.java
Which best describes this axiom: aList.getLength ( ) = ( aList.remove ( i ) ) . getLength ( ) + 1 You cannot remove an item from from existing list that is empty Removing an item from an existing list decreases its length by one Removing an item from an existing list increases the list size by one None of these
