WebAn Example With Trees. We will consider an inductive proof of a statement involving rooted binary trees. If you do not remember it, recall the definition of a rooted binary tree: we start with root node, which has at most two children and the tree is constructed with each internal node having up to two children. A node that has no child is a leaf.
