First, insert the Stream of Keys one by one into the Heap below. Second, after the insertions, perform three deleteMin operations.
Insert a key by drag and dropping it into an empty node of the heap. Delete a key by clicking it and by pressing the "delete" button. After each operation make sure that the heap-order property: "the parent is smaller than its child" is preserved.
It should be noted, however, that drag and drop will swap the source and destination keys with each other.
Some additional problems.
