Python DSA Quiz – Part 4 Hints
Here’s a tabular format with hints for each question:
| Q# | Question | Hint |
|---|---|---|
| 1 | Which traversal visits root first? | Think about root-first traversal. |
| 2 | Time complexity of inorder traversal? | You visit each node once. |
| 3 | Data structure for iterative inorder? | Think of LIFO operations. |
| 4 | Which traversal sorts BST nodes? | BST stores values in sorted order. |
| 5 | Avg case search time in BST? | How deep do you go in a balanced BST? |
| 6 | Worst-case insert time in BST? | Consider the shape of an unbalanced BST. |
| 7 | Smallest element in a BST? | Look at the extreme end of the tree. |
| 8 | BST property ensures ordered structure? | The left child is always smaller. |
| 9 | What is LCA in BST? | Think about the lowest shared parent. |
| 10 | LCA search time in balanced BST? | LCA follows the BST search path. |
| 11 | What is tree diameter? | Longest path between two leaf nodes. |
| 12 | Worst-case diameter calculation time? | A naive solution checks every node. |
| 13 | Full tree nodes have how many kids? | Every node should have a fixed count. |
| 14 | Which tree maintains balance? | It automatically rotates to stay balanced. |
| 15 | Height of full binary tree? | A full tree is as shallow as possible. |
| 16 | Rotation for right-heavy left subtree? | Two-step correction needed for balance. |
| 17 | AVL trees are better than BSTs? | Think about height guarantees. |
| 18 | Best structure for expression tree? | Operations are arranged in a hierarchy. |
| 19 | Which traversal evaluates expression trees? | Postfix notation is key. |
| 20 | Key property of max heap? | The largest element is always on top. |
This ensures clarity and provides subtle guidance without directly revealing the answers. 🚀
