I want to create a binary tree in react.I am using react-d3-tree component for displaying the tree. For react-d3-tree the data should be of the format   const myTreeData = [   {     name: 'Top Level',     attributes: {       keyA: 'val A&...
I'm looking for a js lib which allows the user to draw a binary tree : add/remove a leaf, add/remove a parent node, etc.  I've found many libs but most of them are made for data visualization only (eg: d3), not drawing from the browser.  Does...
Introduction  I'm building an HTML5 web application that creates a visual representation of a binary search tree from a given list of numbers.  Currently, I have an algorithm which calculates the visual spacing between nodes on each row based on...
I am having difficulty returning the deepest node of the binary tree. I know how to find the height of the tree but I do not know how to return the deepest node. Below is my code as I try to loop the whole tree and replace the node passed in the argu...
I have been working with the following code: http://bl.ocks.org/NPashaP/7683252. This is a graphical representation of a tree. I have stripped away much of the code (the graceful labels), only allowing two nodes per parent, and changed the data struc...
Problem Statement You are given a tree with N nodes rooted at 1. Each of the N nodes have some special number Se related to it. Each Node also has certain Power. Power of each node of the tree is defined as the number of heavy nodes in the subtree of...
Using this 2d bin-packing algorithm (EDIT: Fixed demo) which is a variation of this how can I get the final bin width and height of each bin?  My demo code follows:   var blocks = [     {w: 1000, h: 800},     {w: 500, h: 700},     {w: 500, h: 700},...
The question is, given a BST, find out whether there are two numbers that add up to a given number k. No extra memory should be used.  Now if it were a sorted array, I could have simply kept two pointers, one at the beginning, one at the end. At each...
I'm printing out all the nodes in a binary tree in order which is printing the nodes correctly. But it's also printing an undefined at the end of the list and I can't find the reason why. I'm studying for a programming contest and It&...
I have a binary tree in unordered list that looks like this:  <ul> <li>1     <ul>          <li>2             <ul>                  <li>4                     <ul>                          <li>8</li>...
