Heap is a binary tree representation.
Intro to Algo by C.L.R.S (page 159) can be applied part that I had trouble is the derivation.
n / (2^(h+1))nodes of any height h
(i draw some examples which worked)
changed the limit to get better approx for
Leaf nodes are (in 0 based index),
n/2, n/2+1, n/2+2, n/2+3 ... ... ... n
Question: Why does the book (CLRS) use 1 based index where programming languages are based on 0? A common standard among books for pseudocode.
The idea is similar to
Extract-Min. We replace
A[size-1] then, we heapify. Applied that this idea on to solve hackkerrank qHeap.
Deriving the tighter bound I mean in some pages in book.

heap, introduced by Carlsson, using bit in each node to indicate its larger child, to improve the performance of Min-Max Heap. We call it Min-Max Fine Heap. Also a technique similar to the one used by Gonnet and Munro for traditional heaps will be employed for better performance. In the next sections we shall present the structure of the heap, algorithm for carrying out the standard operations on deq
