Web2 days ago · Heaps are binary trees for which every parent node has a value less than or equal to any of its children. This implementation uses arrays for which heap [k] <= heap [2*k+1] and heap [k] <= heap [2*k+2] for all k, counting elements from zero. For the sake of comparison, non-existing elements are considered to be infinite.

WebA binary heap is a complete binary tree. We always insert into a new leaf at the bottom of the tree. The correct location for the new element must be somewhere on the path to the root. We can prove this using the heap property: if a new node is greater than its parent, it must transitively be greater than the parent’s other child, too.
