Write a Common Lisp function that does the following: returns (circle i) if i is a number returns (create-list i-4) if i is a non-numeric atom returns (front-or-back i) if i is a list Please show output as well!

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...

In Haskell, use list comprehension to return all the numbers greater than 18 and divisible by 2 in the list [12, 24, 25, 28, 30, 33, 35]. SHOW OUTPUT AND SOURCE CODE

Write a program in c++ to remove duplication if exists in the linked list. Write 2 separate functions to perform search and other to perform the duplication removal. Note: the above mentioned task is to be performed using singly linked list and in c++

*Needs to be done in scheme interleave* Implement function interleave in scheme, which expects as arguments two lists x and y, and returns asingle list obtained by choosing elements alternately, first from x and then from y. When either x or yruns out, interleave takes the remaining elements from the other list, so that the elements of the resultare exactly the elements of the two argument lists taken together. (interleave '(1 2 3) '(a b c)) -> (1 a 2 b 3 c) (interleave '(1 2 3) '(a b c d e f)) -> (1 a 2 b 3 c d e f) (interleave '(1 2 3 4 5 6) '(a b c)) -> (1 a 2 b 3 c 4 5 6)

Suppose you are given a list (1,2,3,4) and the requirement is to write a Python code segment or a function to double the numbers in that list. Comment your code to state what functional programming features you have introduced in your code.
