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

Implements clone which duplicates a list. Pay attention, because if there are sublists, they must be duplicated as well. Understand the implementation of the following function, which recursively displays the ids of each node in a list Develop your solution as follows: First copy the nodes of the current list (self) Create a new list with the copied nodes Loop through the nodes of the new list checking the value field If this field is also a list (use isinstance as in the show_ids function) then it calls clone on that list and substitutes the value. Complete the code: def L4(*args,**kwargs): class L4_class(L): def clone(self): def clone_node(node): return <... YOUR CODE HERE ...> r = <... YOUR CODE HERE...> return r return L4_class(*args,**kwargs)
Create a DeleteDuplicatesclass which consists of a deleteDuplicates method which takes the nums list as its parameter. Implement the deleteDuplicates method: Check if the input list is null or empty, and return an empty list if so. Initialize a pointer i to keep track of the unique elements. Use a for loop to Iterate through the list using another pointer j which starts at j=1 and goes until j=nums.size(); If the current element at j is not equal to the previous element at i using !nums.get(i).equals(nums.get(j), increment i and set the current element at j to the new position at i using nums.set(i, nums.get(j)). After the for loop ends, return the sublist from the beginning to i + 1, as this will contain all unique elements. Call the deleteDuplicates method with the sample list as argument: Call the deleteDuplicates method and pass the nums list as argument Store the result in a variable result Print the result to the console. Input: [1, 1, 2, 3, 3,…
Implement a list of employees using a dynamic array of strings.Your solution should include functions for printing list, inserting and removingemployees, and sorting lists (use Bubble sort in C++ language).Keep list of employees sorted within the list after insertion.See the following example:How many employees do you expect to have?5 (Carriage Return)Menu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit2 (Carriage Return)Input name of new employee : MikeMenu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit1(Carriage Return)1 . MaryMenu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit
You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…
PROBLEM STATEMENT: In this problem you will need to return the first elementfrom the ArrayList. import java.util.ArrayList;public class RetrieveSpecifiedElement{public static int solution(ArrayList<Integer> list){// ↓↓↓↓ your code goes here ↓↓↓↓return 0; Can you help me with this question The language is Java
PLEASE HELP FAST, java
The program requires me to remove all item for a list, but when doing the test case for it, it only removes one. What would be the problem in this code?Given code: #include "MovieList.h"#include <iostream> using namespace std;// Constructor functionMovieList::MovieList() { top = nullptr; } // Destructor functionMovieList::~MovieList() { MovieNode *p = nullptr; while (top->next != nullptr) { p = top; top = top->next; delete p; } delete top; p = nullptr; top = nullptr; } void MovieList::display(ostream &out) { MovieNode *t = top; int pos = 0; // Function to display the movie list while (t != nullptr) { out << pos << ": " << t->title << endl; pos++; t = t->next; } } int MovieList::count() { MovieNode *t = top; int pos = 0; // Counting based off the movie list while (t != nullptr) { pos++; t = t->next; } return pos; } void…
Suppose that you want an operation for the ADT list that adds an array of items to the end of the list. The header of the method could be as follows: public void addAll( T[ ] items) Write an implementation of this method for the class LinearLinkedList
