I am having trouble implementing a solution using a binary search tree that returns the key of the node based on it's rank in O(N) worst case running time. Every idea i have (listed below) results in O(N^2) or sends me to a dead end. This almost seems impossible. i …

I'm writing maze traversal for a school assignment, and I've got an issue. The X will move through most of the maze, but then it will get stuck at a position and keep cycling through. This is probably because I'm not checking properly to see if it hasn't been to …

Hi! I made a program that accepts random numbers, create a binary tree from it, then traverse it using in-order, pre-order and post-order traversal. The program is working well but my instructor added something else, when the user input numbers, it should be arranged just like an actual tree. The …

Hello, everybody! I've been struggling on implementing the Binary Tree data structure with some standard functions in it. After reading information from many sources and some work on my own, I've came up to this: [url]http://pastebin.com/B6Gtjb61[/url] Problems occur in the main funciton. What I can't understand is why does the …

This snippet defines a function walk() which generically performs a depth-first traversal of a tree, using preorder, inorder or postorder rules. Here, genericity means here that there are no hypotheses on what the tree nodes are or the implementation of the tree. Walk() only needs an arbitrary object used as …

I'm a new member and this is my first post, so be gentle ;) It's been a while since I've gotten a chance to practice with recursion so to say I'm a bit rusty is an understatement. Not to mention I've never implemented it with a linked list. My current …

[CODE]public void treeFormatTraversal(){//begin int level = 0; if(root !=null) treeFormatHelper(root, level); else System.out.println("\nTree is Empty\n"); …

I am currently attempting to write a single [B]recursive[/B] method (per instruction) whereas the items in a binary tree are displayed in a horizontal hierarchical manner (level order traversal). The UML describes the method as: levelOrderTraversal(TreeNode<T> tree, Integer indent) - tree: a node in the binary tree - indent: describes …
