Find n-th node of inorder traversal in binary tree

In a binary tree, the inorder traversal refers to the sequence of nodes visited by recursively traversing the left subtree, then visiting the current node, and finally recursively traversing the right subtree.

The n-th node of the inorder traversal refers to the node that is visited in the n-th position when the tree is traversed in the inorder traversal order.

Find n-th node of inorder traversal

To find the n-th node of the inorder traversal in a binary tree, you can perform an inorder traversal of the tree while keeping track of the nodes visited. When you have visited n nodes, the current node will be the n-th node of the inorder traversal.

One way to implement this algorithm is to use a counter variable to keep track of the number of nodes visited and a recursive function to perform the inorder traversa.
