Question

The class Polynomials is a collection of polynomials of either implementation stored in an instance of the
generic library class List.
class Polynomials
{
private List L;
// Creates an empty list L of polynomials
public Polynomials ( )
{ … } (1 mark)
// Retrieves the polynomial stored at position i in L
public Polynomial Retrieve (int i) (1 mark)
{ … }
// Inserts polynomial p into L
public void Insert (Polynomial p) (1 mark)
{ … }
// Deletes the polynomial at index i
public void Delete (int i) (1 mark)
{ … }
// Returns the number of polynomials in L
public int Size ( )
{ … } (1 mark)
// Prints out the list of polynomials
public void Print ( )
{ … }

Please use C# to answer

Answer 1

1.

Creates an empty list L of polynomials

public polynomials()

{

//creation of empty list of Polynomials

List<Polynomial> list=new List<Polynomial>();

(Or) the provided List l

//we can use Any() to check wheather the list is empty or not

bool check=!l.Any();

if(check)

{

Console.WriteLine("the provided list l is empty");

} else

{

Console.WriteLine("The provided list is not empty");

}

2.

Retrieves the polynomial stored at position i in L

//Can be Done by using Item property

public Polynomial Retrieve (int i) (1 mark)
{

l.Item[i];

}

i.e l.item[2] (it will display polynomial which is storred at 2 location)

3.

// Inserts polynomial p into L
public void Insert (Polynomial p) (1 mark)
{

l.Add(p);

}

4.

// Deletes the polynomial at index i
public void Delete (int i) (1 mark)
{

l.RemoveAt(i)0;//which will remove at index i

}

5.

// Returns the number of polynomials in L
public int Size ( )
{

int count=l.Count; // It will provide number of polynomials of the list

return count;

}

6.

// Prints out the list of polynomials
public void Print ( )
{

foreach(Polynomial polynomial in l)

{

Console.Write(polynomial);

}

}
