Using the Heap.cs and IHeapifyable to pass all tests in Tester.cs

The first $2$ images are the tester class. The words that are cut off on the right hand side aren't relevant as they aren't part of the logic.

The $4$rd image is the Heap.cs$.$ This is what we need to adjust to ensure all the tests in tester class are passed.

We also have the IHeapifyable.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace $\_8.\_1$C$\_$Heaps

$\{$

public interface IHeapifyable

$\{$

K Key $\{$ get; set; $\}$

D Data $\{$ get; set; $\}$

int Position $\{$ get; set; $\}$

$\}$

$\}$

Currently it only pass A D and E tests:
