Q1.The number of edges from the root to the node is called __________ of the tree.
- Height
- Depth
- Length
- Width
Answer:- (B)
Explanations :The number of edges from the root to the node is called depth of the tree.
Explanations :The number of edges from the root to the node is called depth of the tree.
- Height
- Depth
- Length
- Width
Answer:- (A).
Explanations :The number of edges from the node to the deepest leaf is called height of the tree.
Explanations :The number of edges from the node to the deepest leaf is called height of the tree.
- L = 2*I
- L = I + 1
- L = I – 1
- L = 2*I – 1
Answer:- (B).
Explanations :Number of Leaf nodes in full binary tree is equal to 1 + Number of Internal Nodes i.e L = I + 1
Explanations :Number of Leaf nodes in full binary tree is equal to 1 + Number of Internal Nodes i.e L = I + 1
Answer:- (D).
Explanations :Here,
Postorder Traversal: N, P, Q, O, M
Inorder Traversal: N, M, P, O, Q
Root node of tree is the last visiting node in Postorder traversal. Thus, Root Node = ‘M’.
Explanations :Here,
Postorder Traversal: N, P, Q, O, M
Inorder Traversal: N, M, P, O, Q
Root node of tree is the last visiting node in Postorder traversal. Thus, Root Node = ‘M’.
- Every binary tree is either complete or full
- Every complete binary tree is also a full binary tree
- Every full binary tree is also a complete binary tree
- A binary tree cannot be both complete and full
