How do you delete a node from a binary search tree?
An example of an AI chatbot conversation about deleting nodes in binary search trees.
How do you delete a node from a binary search tree?
To delete a node from a binary search tree, you need to consider three cases: if the node is a leaf, has one child, or has two children.
What if the node has two children?
If the node has two children, you find the node's in-order successor (the smallest node in the right subtree), replace the node's value with that, and then delete the successor.
Can you explain how to find the in-order successor?
Sure! The in-order successor of a node is the leftmost node in its right subtree. You can find it by traversing left from the right child.
Are there any special cases I should be aware of?
Yes, if the node to be deleted is the root, you need to handle it carefully, especially if it has two children.
