Circular Lists - C PROGRAM A linear list is being maintained circularly in an array c[0…n-1] with front, and rear set up as for circular queues. a) Draft a formula/algorithm in terms of front, rear, and n for the number of elements in the list.

#include <iostream> using namespace std; #define SIZE 5   //creating the queue using array int A[SIZE]; int front = -1; int rear = -1;   //function to check if the queue is empty bool isempty() { if(front == -1 && rear == -1) return true; else return false; }   //function to enter elements in queue void enqueue ( int value ) { //if queue is full if ((rear + 1)%SIZE == front)    cout<<"Queue is full \n"; else {  //now the first element is inserted  if( front == -1)     front = 0; //inserting element at rear end rear = (rear+1)%SIZE;   A[rear] = value; } }   //function to remove elements from queue void dequeue ( ) { if( isempty() )  cout<<"Queue is empty\n"; else //only one element if( front == rear )  front = rear = -1; else  front = ( front + 1)%SIZE; }   //function to show the element at front void showfront() { if( isempty()) cout<<"Queue is empty\n"; else cout<<"element at front is:"<<A[front]; }   //function to display the queue void…

Python Big-O Notation/Time Complexity Pls answer only if u know big-o Thanks!  Item #3.

Lists and tuples are two distinct data structures.

O b. Remove the O. Remove the second element in the list O d. Remove the element before the last element in the list QUESTION 6 The following code inserts an element at the beginning of the list public void insertBegin(T e) { Node temp = new Node (e); head = temp; temp.Next = head; size++; } O True O False QUESTION 7 what does the following code do?
