WebMar 24, 2024 · A binary tree is a tree-like structure that is rooted and in which each vertex has at most two children and each child of a vertex is designated as its left or right child (West 2000, p. 101). In other words, unlike a proper tree, the relative positions of the children is significant. Dropping the requirement that left and right children are considered unique … WebMar 5, 2024 · Finaly you could use structural induction, that is induction using the inductive definition of the structures you consider. Here that is the notion of a binary tree: which is either empty, or a root and two subtrees. In practise this gives the same proof as strong induction, but you did not need to quantify the number of nodes.
