A crucial element of the Heap_Sort
is the construction of the heap itself. This is achieved by calling a heapify
procedure on some nodes until all nodes satisfy the Max_Heap property( Any node must have a value less or equal to that of its parent ).
The node in position violates the heap property. Once heapify
is applied to it, which position will it be in?

Consider the Heap_Sort
method above. Given a list of numbers A
it will construct a heap and sort them. One line is however missing(line 4). What line of code should be there in order to have a properly functioning Heap_Sort
algorithm.
Note
A crucial element of the Heap_Sort
is the construction of the heap itself. This is achieved by calling a heapify
procedure on some nodes until all nodes satisfy the Max_Heap property( Any node must have a value less or equal to that of its parent ).
Suppose we have a an array with elements. At most, how many calls to heapify
are required to convert it to a heap?
