WebJun 1, 2024 · Take a perfect binary tree B d + 1 of depth d + 1 with B d as part of this tree (just the last layer is missing). We know that each leaf of B d (the tree with depth d) transforms into two leaves in the next layer d + 1. By induction hypothesis B d has L d = N d + 1 2 leaves and N d = 2 d − 1 nodes (we show this number using induction as well).
