PDF-Heaps, Heapsort and Priority QueuesThe application of a purely binary

Numbering of a tree146s nodes for storage in a arrayIf we use the number of a node as an array Index this technique gives us an orderin which we can store tree nodes In an array The tree may be e. ii The height or depth of a binary tree is the maxi mum depth of any node or 1 if the tree is empty Any binary tree can have at most 2 nodes at depth Easy proof by induction EFINITION A complete binary tree of height is a binary tree which contain COL 106.
