Binary Search Tree Operations

MediumPython

Problem

Can you write code to implement a binary search tree and discuss its operations?

Implement a BST supporting insertion, search, deletion, and inorder traversal. Duplicate values must not be inserted.

Contract

Define bst_operations(operations), where each operation is a dictionary with op equal to insert, search, delete, or inorder, and value required for every operation except inorder. Return one result per operation: true or false for mutations and searches, and a sorted list for traversals.

Constraints

  • 1 <= operations.length <= 1000
  • Values are integers in the range [-10^9, 10^9]
  • Duplicate values must not be inserted
  • Each operation has op equal to insert, search, delete, or inorder
  • The value field is present for insert, search, and delete operations
