A default comparator handles primitives automatically; pass a custom one for complex types.\n\n**Delete uses the in-order successor strategy**\nWhen deleting a node with two children, it finds the smallest node in the right subtree (in-order successor), copies its value up, then deletes the successor — this preserves BST ordering with minimal restructuring.\n\n**Method chaining**\n`insert` and `delete` return `this`, so you can chain calls like `bst.insert(1).insert(2).delete(1)`.\n\n**All three traversals included**\n- `inorder` (L → Root → R): produces sorted output, the most commonly needed\n- `preorder` (Root → L → R): useful for serialization/cloning\n- `postorder` (L → R → Root): useful for safe deletion or expression evaluation\n\n**Time complexities**\n\n| Method | Average | Worst (skewed tree) |\n|---|---|---|\n| `insert` | O(log n) | O(n) |\n| `search` / `contains` | O(log n) | O(n) |\n| `delete` | O(log n) | O(n) |\n| `inorder` / `preorder` / `postorder` | O(n) | O(n) |\n| `findMin` / `findMax` | O(log n) | O(n) |\n| `height` / `size` | O(n) | O(n) |\n\nIf you need guaranteed O(log n) performance regardless of insertion order, consider extending this into a self-balancing tree like an AVL or Red-Black tree." + }, + "proxy": { + "totalMs": 27861, + "headerMs": 4, + "ttfbMs": 3324, + "firstContentMs": 3324, + "streamMs": 24537, + "textLength": 7426, +

**Custom `Comparator`** | Makes the tree flexible for non-primitive types (e.g., objects) |\n| **Interface `IBinarySearchTree`** | Enforces the public API contract and is easy to extend or mock |\n| **`Nullable` alias** | Cleaner than repeating `T \\| null` everywhere |\n| **In-order successor for delete** | Standard, correct approach for two-child deletion |\n| **Duplicate values ignored** | Common BST convention; easily changed to allow duplicates |\n| **Recursive implementation** | Clear and readable; for very deep trees, an iterative version avoids stack overflow |\n\n## Complexity Summary\n\n| Operation | Average Case | Worst Case (skewed tree) |\n|---|---|---|\n| `insert` | O(log n) | O(n) |\n| `delete` | O(log n) | O(n) |\n| `search` | O(log n) | O(n) |\n| `inorder` | O(n) | O(n) |\n\nFor guaranteed O(log n) worst-case performance, consider extending this into a self-balancing tree such as an AVL tree or Red-Black tree." + } + } +] \ No newline at end of file diff --git
