I came across this problem online and I wrote the following function to check if a BST is valid. However, what I don't fully understand is how max/min change from null to values that you can compare against.  so in the following function:  //Give...
I try to create a BST with the following code, nums = [4,5,8,2]  var TreeNode = function (val) {     this.val = val;     this.left = this.right = null;     this.count = 1; }  var constructBST = function(nums) {     if (nums.length === 0) return null;...
I have built a VR application similar to WebVR-Vive-Dragging that allows to interact with numerous 3d objects using VR controllers. This means that a user can grab an object with a VR controller and can move or scale it.   In my application, a collis...
Problem: given a binary search tree, print out the longest path.   Approach: Store the possible depths at each level and filter out the longest one. The time complexity of this must be at least O(n) because we are calculating the diameter of the tree...
Started writing the removal function for an unbalanced BST structure. Manually running some tests for the first case (node has no children). Decided to run it on a tree of size 1 (just the root), and for some reason it does not seem to be reassigning...
Currently learning about DFS and just have a few questions about the mechanics of how it works.  Repl link below due to the lengthy nature of the code:  https://repl.it/@Stylebender/DFS-Recursive   Is the base case of the traverseInOrder function jus...
I built a function to get values from a binary tree (InOrder) . Now I would like to modify that function so it would work with a n-ary tree.  I would appreciate your help.  function stringFromInOrder(tree, position) {     if (!tree) {         return...
I'm new to nodeJS javascript and I have a simple problem here.  I have a Binary Search Tree (BST) in javascript.  Each Node has a value, and a count.  We're inserting words into the BST such that each Node represents a word.  Upon insertion,...
what are the possible ways to print an AVL tree data? it is possible to do that with ANTLR to visualize the data in every node so that way i can also verify the balancing?  thanks!...
I am trying to console every data in a binary tree. My main problem is that I want to implementing in a recursive way. Basically I have this code so far:  this.levelOrder = function (root) {     if (root.data != null) {         console.log(root.data)...
