What is the defining property of a Binary Search Tree (BST)?
What is the defining property of a Binary Search Tree (BST)?
- All nodes in the left subtree have values less than the root node, and all nodes in the right subtree have values greater than the root node. (correct)
- Each node has a unique value.
- All nodes have at most two children, a left child and a right child.
- The tree is always perfectly balanced.
What is the purpose of recovering a corrupted Binary Search Tree (BST)?
What is the purpose of recovering a corrupted Binary Search Tree (BST)?
- To add new nodes to the tree while maintaining the BST property.
- To restore the tree's structure by identifying and correcting two misplaced nodes that violate the BST property. (correct)
- To convert the BST into a different type of binary tree.
- To ensure the tree is perfectly balanced.
