In-Order Traversal
Last updated
What is In-Order Traversal?
In order traversal is a method for traversing binary trees. This method follows a specific order: Left Node, Root Node, then Right Node (L-N-R). Starting from the leftmost node of the tree, you first visit the left subtree, then the root node, and finally the right subtree. If the tree is a binary search tree, in order traversal will output the values of the nodes in the tree in ascending order. This traversal method is recursive in nature, as it requires each subtree to be visited in the exact same way.

In-Order Traversal: common questions
Can I learn In-Order Traversal in Hindi?
This lesson is written in English. Once you sign in, open it in the interactive course and ask the AI tutor to explain In-Order Traversal in Hindi or Hinglish. The tutor answers from this lesson’s own text, so it stays on the syllabus, and it runs on your own Google, OpenAI or Anthropic key.
Is this In-Order Traversal tutorial for beginners?
It is lesson 62 of 107 in the free Data Structures & Algorithms roadmap, in stage 11, Advanced Data Structures. If you are new to Data Structures & Algorithms, start from stage 1 and come back here in order; if you already know the earlier stages, this lesson stands on its own.
