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.

Can you explain the three cases in more detail?

Sure! If the node is a leaf, simply remove it. If it has one child, replace the node with its child. If it has two children, find the in-order successor, replace the node with it, and then delete the successor.

What is an in-order successor?

The in-order successor of a node is the smallest node in its right subtree. It helps maintain the properties of the binary search tree after deletion.

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 to ensure the tree remains balanced.
