- I need help being able to make a function that adds an item to the back of a doubly linked list to add an animal to the end of the list in C++ Here's what I got so far with the code #include <iostream> #include <string> using namespace std; class node { public: string data;// Data item node* next; // Point to next node }; class linkedList { public: // Variables? (Attributes) node* headptr; // Functions (methods) linkedList() { headptr = nullptr; } // Add an item to front of list void addFront(string x) { // Declare a pointer variable node* p; // Create a new node, and store its address in p p = new node; // Put x into data field of the new node // Can also put p -> data = x, same thing. (*p).data = x; // Set next pointer of node to previous front item (*p).next = headptr; //Update the…Use Python for this question: Implement a function findMixedCase that accepts a single argument, a list of words, and returns the index of the first mixed case word in the list, if one exists, (a word is mixed case if it contains both upper and lower case letters), and returns -1 if the all words are either upper or lower case Output for this question is in the attached image:PYTHON: Give a recursive implement to the following function: def split_by_sign(lst, low, high) The function is given a list lst of non-zero integers, and two indices: low and high (low ≤ high), which indicate the range of indices that need to be considered. The function should reorder the elements in lst, so that all the negative numbers would come before all the positive numbers. Note: The order in which the negative elements are at the end, and the order in which the positive are at the end, doesn’t matter, as long as all he negative are before all the positive.

- Construct recursive versions of the library functions that: a. calculate the "sum" of a list of numbers. b. "take" a given number of elements from the beginning of a list. c. select the "last" element of a non-empty list .Computer Science Given two polynomials in form of strings. How to use Java program that adding, subtracting, and multiplying two polynomials using singly linked lists. Using a singly linked list to represent a polynomial. Each term will be saved in a node in the list. The length of the list will be the number of terms in the given polynomial. Input: The input will be two polynomials in the following form of strings, for example: "(-4.5)X^1 + (-2.5)X^0 + 1X^3" "1X^2 + 1X^0" Output: Polynomial p: X^3 -4.5X -2.5 Polynomial q: X^2 + 1.0 p+q: X^3 + X^2 -4.5X -1.5 p-q: X^3 -X^2 -4.5X -3.5 p*q: X^5 -3.5X^3 -2.5X^2 -4.5X -2.5 import java.util.StringTokenizer; public class Term { private double coeff; private int pow; } import java.util.StringTokenizer; public class Polynomial { private SinglyLinkedList<Term> p; public Polynomial(String st) { } public Polynomial add(Polynomial q) { } public Polynomial subtract(Polynomial q) { } public Polynomial multiply(Polynomial q) { } public…All the problems are to be coded in Python/Java. You must explicitly solve each problem below using your own logic. For example, Do not use existing library functions, such as sum( ), which computes the sum of a list. Instead, you must use for/while loop to sum up the items in a list. a. Write code for a CharList class which converts a string to a linked list of characters in the string. * b. Add a class member function which outputs if the linked list in Problem a. is a palindrome. What is the Big-O upper bound? c. What change could be made to the class definition in Problem a. to make your solution in Problem b. more efficient? Explain. What is the Big-O upper bound? Hint: Think of how the palindrome determination problem is solved for a regular string. d. Add a method to the classic List class we discussed in class that reverses the list. That is, if the original list is A -> B ->C, all of the list's links should change so that C-> B-> A. Make your solution as efficient as possible.…
- python 3 Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will read a list of one word names, then use a recursive method to create and output all possible orderings of those names, one ordering per line. When the input is: Julia Lucas Mia then the output is (must match the below ordering): Julia Lucas Mia Julia Mia Lucas Lucas Julia Mia Lucas Mia Julia Mia Julia Lucas Mia Lucas Julia question: is it any way that i can use ('if' statement as base case, and 'else' statement as recursive case) in the code below? thanks. code: def all_permutations(permList, nameList):# TODO: Implement method to create and output all permutations of the list of names.def createPermutationsList(nameList):f = len(nameList) if f == 0:return [] if f == 1:return [nameList] permList = [] for i in range(f):newList = nameList[i]remaining = nameList[:i] + nameList[i+1:]for p in createPermutationsList(remaining):permList.append([newList] + p)…Write a program called Recursive_fibonacci.java that implements a recursive function for computing the nth term of a Fibonacci Sequence. In the main method of your program accept the value of n from the user as a command-line argument and then call your function named Fibonacci with this value. The output should look exactly like what is pictured below.What would be the best way to check if a list is strictly ascending in Python 3? My instructions for the task are: Determine whether the sequence of items is strictly ascending so that each element is strictly larger (not just merely equal to) than the element that precedes it. Return True if the list of items is strictly ascending, and return False otherwise. Note that the empty sequence is ascending, as is also every one-element sequence, so be careful that your function returns the correct answers in these seemingly insigni0icant edge cases of this problem. (If these sequences were not ascending, pray tell, what would be the two elements that violate the requirement and make that particular sequence not be ascending?).
