Implement different search algorithms : BST from scratch - In-order traversal

The video tutorial covers the inorder traversal method for binary search trees, explaining how to output node values in sorted order. It details the implementation process, including recursive traversal and base cases. The tutorial also demonstrates testing the traversal and formatting the output to display node values on the same line. Homework is assigned to implement preorder and postorder traversal methods, with a preview of the next video focusing on building a search method for the tree.

What is the significance of checking if a node is 'none' during traversal?

How can the output of the traversal be formatted to display in the same line?

What homework was assigned related to other traversal methods?
