binary-heap

Trying to think of a lower bound to the position of say, the nth largest key in a max-heap. Assuming the heap's laid out in array. The upper bound's min(2^n-2, array size -1) i think, but is it always lower bounded by 0?

How to prove that: Let's say we have two binary heap trees H1 and H2 with size N. If their inorder traversals are the same, prove that H1=H2 by induction on N. >>> More

After removing the minimum element in a binary heap, i.e. after removing the root, why is the last leaf then assigned to the root and sifted down? Why not take the lesser child of what used to be the root and just keep sifting up all the children? Isn't this the same amount of operations, so why… >>> More
Pointer-based binary heap implementation

Is it even possible to implement a binary heap using pointers rather than an array? I have searched around the internet (including SO) and no answer can be found. The main problem here is that, how do you keep track of the last pointer? When you insert X into the heap, you place X at the last pointer… >>> More

Efficient heaps in purely functional languages

as seen on Stack Overflow - Search for 'Stack Overflow'
As an exercise in Haskell, I'm trying to implement heapsort. The heap is usually implemented as an array in imperative languages, but this would be hugely inefficient in purely functional languages. So I've looked at binary heaps, but everything I found so far describes them from an imperative viewpoint… >>> More
