How do you delete a node from a binary tree?

To delete a node from a binary tree, you first need to find the node. If it's a leaf node, simply remove it. If it has one child, replace it with its child. If it has two children, find the inorder successor or predecessor, copy its value to the node, and then delete the successor or predecessor.

What if the node I want to delete is the root?

If the root node is the one you want to delete, you can follow the same process. If it has two children, find the inorder successor or predecessor, replace the root's value with that, and then delete the successor or predecessor.

Can you explain what an inorder successor is?

The inorder successor of a node is the node with the smallest value in its right subtree. It's the next node in the inorder traversal of the tree.

Are there any special cases I should be aware of?

Yes, be cautious with nodes that have two children, as you need to ensure you properly replace the node and maintain the tree's structure.
