Questions & Answers

Q: What is a binary search tree?

A binary search tree is a data structure where lesser values are stored to the left of a parent node, and larger values are stored to the right, following specific rules for insertion and retrieval.

Q: How is a vertex defined during tree traversal?

A vertex is any node that is visited for the first time during traversal. It signifies the starting point for printing the node's value and exploring its children.

Q: Why is it essential to follow the rules of in-order, pre-order, and post-order traversal?

Following the rules of traversal ensures that nodes are visited in a specific order, allowing for accurate printing and exploration of binary tree structures.

Q: What output is expected for in-order traversal of a binary search tree?

In-order traversal of a binary search tree results in a sequence of values in increasing order, reflecting the nature of binary search tree storage.
