Binary Tree Program to Insert Node | Data Structure Using C

TL;DR

This video explains the process of creating a binary search tree through a program implementation.

hello dear students i am samir velankar i welcome all of you to this next video on binary search tree in the previous video we saw fundamentals of binary search tree its appearance is here the structure of binary search tree was seen and how do you create binary search tree by using the ordering that is less than and greater than ordering we saw fo...

Key Insights

• 👨‍🔬 Binary search trees are created by adding nodes based on their values in a specific order.
• 👶 The insertNode function is responsible for inserting new nodes into the binary search tree.
• 👶 Pointers and comparisons are used to find the appropriate position for each new node.

Questions & Answers

Q: How is a binary search tree created by adding nodes?

Nodes are added sequentially based on their values compared to the existing nodes in the tree. Smaller values go to the left, and larger values go to the right.

Q: What does the insertNode function do?

The insertNode function inserts a single node at a time into the binary search tree. It takes in the address of the root node and the value to be inserted.

Q: How does the program determine where to insert the new node?

The program uses two pointers, a and b, to traverse through the tree and find the appropriate position for the new node. Depending on the value being inserted, the pointers move left or right.

Q: What happens if the root node is null when calling the insertNode function?

If the root node is null, meaning the tree is empty, the root pointer is initialized to null. The new node becomes the root node in this case.

Q: How are nodes printed in a binary search tree?

Nodes in a binary search tree can be printed in different methods: in order, pre-order, and post-order. These methods will be explained in subsequent videos.

Summary & Key Takeaways

• The video starts by introducing the structure of a binary search tree and its ordering system.

• The process of creating a binary search tree by adding nodes sequentially is demonstrated.

• The video then explains the program code for creating a binary search tree, including the structure declaration, node insertion function, and traversal function.
