Leaves of binary tree

Nettet8. mar. 2024 · 1 Suppose that T has n nodes, ℓ of which are leaves; then the sum of the degrees of the nodes is 2 + 3 ( n − ℓ − 1) + ℓ = 3 n − 2 ℓ − 1, since the root has degree 2, each of the other n − ℓ − 1 non-leaves has degree 3, and each leaf has degree 1. This is twice the number of edges, so T has 3 n − 1 2 − ℓ edges.
