Write a Scheme function named elements which counts the number of elements in a list; for example: (elements '(1 (2 (3) 4) 5 6)) is 6, while the length of the same list is 4.

Provide full C++ code Building a playlist (of songs) using a linked list and making some operations such as adding songs, removing songs, shuffling them, etc. (Some parts of this lab will closely follow lab 08 - it is imperative that you complete that lab before working on this project). A Node representing a song has the following data members (similar to struct Node of lab 08, except it doesn't have one member for storing data): string uniqueID  string songName string artistName int songLength Node* nextNodePtr Your code must have the following three files: Playlist.h - Class declaration for a linked list of Nodes (very similar to lab 08 but with some changes to methods, as described below) with following private data members: private:Node* first;Node* last;int size; Playlist.cpp - Class definition main.cpp - main() function Checkpoint A For checkpoint A, you need to build a playlist (of songs) by readings data members of several songs from a file and printing them. Implement…

Please help with C++Priority Queue question in C++ language. Sample output also in image. Thanks.

For the given question use C language (DO NOT USE C++ OR JAVA). Write a complete C program to build an unordered Linked List with exactly 4 nodes, which contains randomly generated integer data. Program should also display all the data in the linked list by looping. Example : Start 15 8 24 17
