Consider a binary tree $$T$$ that has $$200$$ leaf nodes. Then, the number of nodes in $$T$$ that have exactly two children are ________.

A complete n-ary tree is a tree in which each node has n children or no children. Let I be the number of internal nodes and L be the number of leaves in a complete n-ary tree. If L...

In a binary tree, the number of internal nodes of degree 1 is 5, and the number of internal nodes of degree 2 is 10. The number of leaf nodes in the binary tree is

Which of the following statements is false?

A binary tree T has n leaf nodes. The number of nodes of degree 2 in T is:

If the no of leaves in a tree is not a power of 2,then the tree is not a binary tree.
