What is the time complexity of the shiftright function

Question

Lab Assignment

1) Update the specifications of the DeleteItem function of the array version of the class UnsortedType as follows:

a) If the ItemType to be deleted is not found in the list, then the list remains unchanged.

b) All copies of the item to be deleted are removed from the list, if they exist.

What is the time complexity of the DeleteItem function and why?

2) Create a function called ShiftRight that shifts the contents of the list one index to the right bringing the last item (index = length -1) of the list to the front (index = 0) of the list.

What is the time complexity of the ShiftRight function and why?

Use the following driver to test your implementations:

#include "unsorted.h"
#include
using namespace std;

int main(){

UnsortedType classList;
classList.PutItem(ItemType(4));
classList.PutItem(ItemType(5));
classList.PutItem(ItemType(4));
classList.PutItem(ItemType(4));
classList.PutItem(ItemType(8));

cout << "(original) length: " << classList.GetLength() << endl;
classList.ResetList();
classList.Print();

classList.ShiftRight();
cout << "(shifted right) length: " << classList.GetLength() << endl;
classList.ResetList();
classList.Print();

classList.DeleteItem(ItemType(4));
cout << "(delete all 4s) length: " << classList.GetLength() << endl;
classList.ResetList();
classList.Print();

classList.ShiftRight();
cout << "(shift right) length: " << classList.GetLength() << endl;
classList.ResetList();
classList.Print();
}

Also, use the following ItemType class, as provided in your source code:

class ItemType
{
public:
ItemType();
RelationType ComparedTo(ItemType) const;
void Print(std::ostream&) const;
void Initialize(int number);
private:
int value;
};

Format your assignment according to the following formatting requirements:

1. The answer should be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.

2. The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.

3. Also include a reference page. The Citations and references should follow APA format. The reference page is not included in the required page length.
