WebA binary heap is a complete binary tree which satisfies the heap ordering property. The ordering can be one of two types: the min-heap property: the value of each node is greater than or equal to the value of its parent, with the minimum-value element at the root. the max-heap property: the value of each node is less than or WebTo implement a heap with a binary tree with O (log n) time complexity, you need to store the total number of nodes as an instance variable. Suppose we had a heap of 10 total nodes. If we were to add a node... We increment the total number of nodes by one. Now we have 11 total nodes.
