PPT-1 Heaps

A heap is a binary tree A heap is best implemented in sequential representation using an array Two important uses of heaps are i efficient implementation of priority queues ii sorting Heapsort. 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 Kids are often in a hurry to get somewhere play sport want to be first in line etc and so kids often have bruise s in many colours decorating some parts of their bodies What is a bruise Bruises are caused by banging yourself against something or bei Data .
