Question

The no of external nodes in a full binary tree with n internal nodes is?

Answer 1

about 8 internal nodes in full binary tree

Answer 2

Answer:

The no of external nodes in a full binary tree with n internal nodes is?

Explanation:

The no of external nodes in a full binary tree with n internal nodes is n+1 external nodes.

• The complete Binary Tree are n+1 external nodes.
• A binary tree can also have zero (0), one nodes and it can also have maximum of two nodes.
• Also the binary tree have two nodes in itself that is right node and left node.
• The external node is the one without child branch whereas the internal nodes are one with at least one of its child branch.
• We can define the size of any binary tree by the number of its nodes.
• Therefore the number of external nodes in a full binary tree with n internal nodes is n+1 external nodes.

Hence, the no of external nodes in a full binary tree with n internal nodes is n+1 external nodes.
