degree of a tree
Module 8: Trees and Graphs
The number of subtrees of a node is called its degree For example node A is of degree three while node E is of degree two The maximum degree of all nodes is |
Let's understand what a level in a Binary Tree means.
A level is the number of parent nodes corresponding to a given a node of the tree.
It is basically the number of ancestors from that node until the root node.
So, for the root node (topmost node), it's level is 0, since it has no parents.
What is the degree and order of a tree?
Degree represents the lower bound on the number of children a node in the B Tree can have (except for the root). i.e the minimum number of children possible.
Whereas the Order represents the upper bound on the number of children.
How do you measure the degree of a tree?
Stand a distance back from the tree at a point where you have a good view of the crown.
Use the clinometer to determine the angle from your position to the highest point on the tree.
What is degree of a tree example?
The number of subtrees of a node is called its degree.
For example, node A is of degree three, while node E is of degree two.
The maximum degree of all nodes is called the degree of the tree.
