Solution Review: Delete Node
Understand how to delete nodes in a binary search tree efficiently in Go. Explore three deletion scenarios: nodes with no children, one child, and two children, along with practical code explanations to apply these techniques.
Solution
For this solution, there can be three cases for the node that needs to be deleted. Let’s call this node x for simplicity. We’ll discuss each case one-by-one.
Case 1: node x has no children
This is a trivial case, in which we just delete the node (by changing the parent node so that it does not point to x ...
