Recursive Binary Search Tree Insert
- by Nick Sinklier
So this is my first java program, but I've done c++ for a few years. I wrote what I think should work, but in fact it does not. So I had a stipulation of having to write a method for this call:
tree.insertNode(value);
where value is an int.
I wanted to write it recursively, for obvious reasons, so I had to do a work around:
public void insertNode(int key) {
Node temp = new Node(key);
if(root == null) root = temp;
else insertNode(temp);
}
public void insertNode(Node temp) {
if(root == null)
root = temp;
else if(temp.getKey() <= root.getKey())
insertNode(root.getLeft());
else insertNode(root.getRight());
}
Thanks for any advice.
