Question

Given a binary search tree and a number, write a Java program to remove all nodes that are less than the number. (All I need is the method that removes everything less than the number) I can assume the Binary search tree has a working remove method, however I want to find a more efficient way of doing this, rather than calling remove on every node less than the number.

Answer 1

To efficiently remove all nodes less than a given number in a binary search tree in Java, we can use a recursive approach.

Step-by-step explanation:

To efficiently remove all nodes less than a given number in a binary search tree in Java, we can use the following approach:

1. We start from the root of the tree and check if the value is less than the given number.
2. If it is less, we set the left child to null and recursively call the method on the right child.
3. If it is greater or equal, we recursively call the method on both the left and right child.

This approach avoids the need to call the remove method on each node less than the given number, resulting in a more efficient solution.
