Which of the following statements about trees is correct?
Recursion is not a useful technique for tree traversal
What is the maximum number of children a parent node can have in a binary tree?
2
What is a key characteristic of a tree data structure?
It represents a hierarchical structure
What is a common use of recursion in tree traversal?

Which of the following is true about a tree data structure?

What is the purpose of recursion in tree traversal?
To process each child node before the parent node
Which type of tree limits the number of children for each parent to at most two?
Binary tree
What is the top-most node in the hierarchy of a tree called?
Root node
How are trees different from linear data structures?
Trees can only be represented in a single straight line, while linear data structures can have branching paths
Study Notes
Tree Data Structure
- The root node of a tree is the top-most node in the hierarchy.
Characteristics of Trees
- A key characteristic of a tree data structure is that it is a non-linear data structure.
Binary Trees
- In a binary tree, each parent node can have a maximum of two children.
- A binary tree is a type of tree that limits the number of children for each parent to at most two.
Tree Traversal
- Recursion is commonly used in tree traversal to traverse the tree.
- The purpose of recursion in tree traversal is to traverse the tree.
Trees vs. Linear Data Structures
- Trees are different from linear data structures because they are non-linear.
