1. Write a non-recursive traversal of a Binary Search Tree using constant space and O(n) run time

This is not homework, this is an interview question. The catch here is that the algorithm should be constant space. I'm pretty clueless on how to do this without a stack, I'd post ...

2. Edit the nodes in a binary tree in Java

Okay. I have a binary tree, and this is what I want to do with it: For each node in original tree: If it's not a leaf, replace it with a leaf ...

3. Recursive Traverse of Binary Tree Not Terminating At Return Statement

I have created a class that populates a binary tree with morse code. Where traversing to the left signifies a DOT and traversing to the right signifies a DASH. ...

4. Skip nodes during binary tree traversal

I need to traverse a binary tree, skipping the children of any node for which a condition is met. This implements a tree-guided clustering approach; the leaves of a subtree are considered ...

5. binary tree traversal

i have made an binary tree, and im trying to make an postorder traversal. I have already made an preorder traversal - which i though was what i needed. But after ...

7. Node labelling within a tree using depth-first traversal

Hello, I'm currently trying to work my way through Java and need some advice on using and traversing trees. I've written a basic JTree program, which allows the user to add and delete nodes. Each new node is labelled in a sequential order and not dependent upon where they are added to the tree. Basically, what is the best way to ...

8. Tree Traversal

I need help! I'm writing code to traverse a tree, find a given character, and then print out it's path labels. It's basically for Huffman coding. I've written the following, but it just goes on and on. Can someone help? Thanks! private static String traverse(HuffNode r, char c) //this method traverses the tree for codewords; code is backwards { String result ...

10. Traversing Tree of Hanoi

John, Usually the Towers of Hanoi problem is created in such a way as the recursive traversal of the data creates a "binary tree" in code. And usually it is considered in-order. But given a general binary tree one traverses the orders by recrusive moves, such as: for in-order: Traverse( type root ) { if root == null quit Traverse ( ...

12. [UnSolved] Traversing Trees problem

public void traverse(Node node, List path) { if (node != null) { // if we haven't fallen off the tree list.add(node); if (node.left == null && node.right == null) // it's a leaf swapPayloads(path); else { traverse(node.right, path); // right first, left last traverse(node.left, path); } list.remove(list.size()-1); // remove last node from the path } }

14. traversing a binary tree

Hi I've written the following code for converting Postfix to Infix,it reads a string then reads it letter by letter ,a stack and a Tree is used,and I want to traverse the last object that has poped from the stack,in the following code I used this line: System.out.println((Character)(((TreeNode)stack.pop()).data)); but it only prints the root of the tree,I tried to traverse it ...

18. Problem with level by level tree traversal

The level will add hence for your example it will give me level 0 - 2 level 1 - 1 level 2 - 3 But for node 3 it shouldn't be level 2, it should be level 1. May i know what wrong with my code? Or can you provide any explaination or eaxmple?

19. Need help with tree traversal...

I'm importing a separate class to construct my tree. Sorry if that wasn't clear. I'm trying to implement the method I showed before but it doesn't seem like there is a way to get a hold of the root node. This is my first project with binary search trees and I've run out of ideas. Any suggestions...

21. Traversing a tree with breadthFirstEnumeration

Hi all, I'm trying to traverse a DefaultMutableNode tree using breadthFirstEnumeration. However, while traversing I need to remove some branches and continue with the Enumeration. Do you know any way to preserve the Enumeration after removing a branch??? For example: for(Enumeration en = trial.breadthFirstEnumeration(); en.hasMoreElements() { DefaultMutableTreeNode currentNode = (DefaultMutableTreeNode)en.nextElement(); if((String)currentNode.getUserObject() == "2") { ((DefaultMutableTreeNode)(currentNode)).removeAllChildren(); } System.out.println((String)currentNode.getUserObject()); } This code traverses ...  | Contact Us | Privacy Policy
