WebDefinition 6.5.A binary tree is a tree in which every internal node has degree three. Definition 6.6.A rooted tree is a tree with a distinguished leaf node called the root node. Warning to the reader: The definition of rooted tree above is common among biologists, who use trees to represent evolutionary lineages (see Darwin’s sketch at WebAug 29, 2024 · The nodes in 2.(1) are the nodes that are not in the subtree with node vi as root. And the nodes in 2.(2) are the nodes of the subtree with node ui as root. This lead me to think about segment tree, which is much faster when it comes to updating and query. But we can not apply segment tree directly here.
