Data Structures | Heap | Question 9
What are the necessary condition for a Tree to be a heap?
(A)
the tree must be complete.
(B)
Every Root value is greater or smaller than the children’s value.
(C)
Both A and B
(D)
None
Answer: (C)
Explanation:
A Heap is a special Tree-based data structure in which the tree is a complete binary tree.
Types of Heap Data Structure
Generally, Heaps can be of two types:
- Max-Heap: In a Max-Heap the key present at the root node must be greatest among the keys present at all of its children. The same property must be recursively true for all sub-trees in that Binary Tree.
- Min-Heap: In a Min-Heap the key present at the root node must be minimum among the keys present at all of its children. The same property must be recursively true for all sub-trees in that Binary Tree.
Hence Option(C) is the correct answer.
