Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a binary search tree with the values: 30, 20, 40, 10, 25, 35, 50. Perform an inorder traversal and illustrate the steps.

💡 Hint: Remember to traverse left before visiting the node!

Challenge 2 Hard

Consider the following BST: 50 (root), 30 (left), 70 (right), 20 (left of 30), 40 (right of 30), 60 (left of 70), 80 (right of 70). What would be the inorder traversal output?

💡 Hint: Follow the left, current, right strategy closely.
