Given the binary tree and you have to find out the n-th node of inorder traversal.
Input : n = 4 10 / \ 20 30 / \ 40 50 Output : 10 Inorder Traversal is : 40 20 50 10 30 Input : n = 3 7 / \ 2 3 / \ 8 5 Output : 8 Inorder: 2 7 8 3 5 3th node is 8
We do simple Inorder Traversal. While doing the traversal, we keep track of count of nodes visited so far. When count becomes n, we print the node.
Below is the implementation of the above approach.
Time Complexity: O(n)
