Circular linked list is a form of the linked list data structure where all nodes are connected as in a circle, which means there is no NULL at the end. Circular lists are generally used in applications which needs to go around the list repeatedly. struct Node * insertTONull (struct Node *last, int data) // This function is only for empty list 11 5 15 struct Node insertStart (struct Node +last, int data) In this question, you are going to implement the insert functions of a circular linked list in C. The Node struct, print function and the main function with its output is given below: struct Node { int data; struct Node *next; }; struct Node insertEnd (struct Node *last, int data) void print(struct Node *tailNode) struct Node *p; if (tailNode -- NULL) struct Node * insertSubseq (struct Node *last, int data, int item) puts("Empty"); return; p - tailNode → next; do{ printf("%d ",p→data); p - p > next; while(p !- tailNode →next); void main(void) { struct Node *tailNode - NULL; tailNode -…
Q2) Given a singly linked list, write a function to find the last element from the beginning whose n%k == 0, where n is the number of elements in the list and k is an integer constant. For example, if n = 19 and k = 3 then we should return 18 th node. %3D
use code below in part with bts #include <stdio.h>#include <stdlib.h>#include <time.h> typedef struct node_struct {int item;struct node_struct *next;} node; /*** 10->NULL* We want to insert 20* First call ([10], 20) [not complete]* {10, {20, NULL}} To compute the conditional probabilities you need to determine unigram andbigram counts first (you can do this in a single pass through a file if you do thingscarefully) and store them in a Binary Search Tree (BST). After that, you can computethe conditional probabilities.Input filesTest files can be found on (http://www.gutenberg.org/ebooks/). For example,search for “Mark Twain.” Then click on any of his books. Next download the “PlainText UTF-8” format.In addition, you should test your program on other input files as well, for which youcan hand-compute the correct answer.Output filesYour program must accept the name of an input file as a command line argument.Let's call the file name of this file fn.

LAB: Playlist (output linked list) Given main(), complete the SongNode class to include the function PrintSongInfo(). Then write the PrintPlaylist() function in main.cpp to print all songs in the playlist. DO NOT print the head node, which does not contain user-input values. Ex: If the input is: Stomp! 380 The Brothers Johnson The Dude 337 Quincy Jones You Don't Own Me 151 Lesley Gore -1 the output is: LIST OF SONGS ------------- Title: Stomp! Length: 380 Artist: The Brothers Johnson Title: The Dude Length: 337 Artist: Quincy Jones Title: You Don't Own Me Length: 151 Artist: Lesley Gore
