Compute the depth of a node v in tree T: int depth(T, v) Algorithm: int depth(T,v) {if T.isRoot(v) return 0 return 1 + depth(T, T.parent(v))} Analysis: • O(number of ancestors) = O(depth_v) • in the worst case the path is a linked-list and v is the leaf • ==> O(n), where n is the number of nodes in the tree Algorithms on trees: Depth
We define the degree of a node n as follows. Usually, we store data on the tree nodes. We define the label(n) of a node n as the data stored on the node. We define the level/depth of a node n as follows. We define the height of a node n as follows. Why do we need to take a union with 0 in the definition of height? Why do we need trees?
22 Οκτ 2024 · Learn the fundamentals of Tree Data Structure: its representation, importance, types, operations, implementation, applications, advantages and disadvantages
Trees are a fundamental data structure in computer science, used to represent hierarchical relationships. This tutorial covers several key types of trees. Binary Trees: Each node has up to two children, the left child node and the right child node.
Here, we’re not showing how to implement trees, or how to store them in a data structure. We’re just introducing type tree —without any operations at the moment. The first image to the right is not a tree. A tree cannot have a node that has an edge leading from itself back to itself.
