12:54 What's the difference between the number of leaves and the number of edges of a recursion tree? Aren't they the same?

[@junzhai1715]

number of leaves is the numbers of nodes at the bottom level. number of edges is the all edges in the tree not just at the bottom. Obviously, there are more edges than leaves if level > 1.
