Rooted tree data structure
WebRecursive definition of rooted tree 18 A tree T is a set of 𝑛 nodes such that: • if 𝑛 > 0 then one of the nodes is the root r • if 𝑛 > 1 then the 𝑛 − 1 non-root nodes are partitioned into k non-empty subsets T1, T2, …, Tk, each of which is a tree (called a “subtree”), and the roots of the subtrees are the children of root node r. WebA rooted tree is a tree in which a special ("labeled") node is singled out. This node is called the "root" or (less commonly) "eve" of the tree. Rooted trees are equivalent to oriented …
