How i get the PreOrder,InOrder,PostOrder to work?

Here are my current code and implementation, see InOrder(),PreOrder(),PostOrder(). I have a reference from Geek4Geek (https://www.geeksforgeeks.org/tree-traversals-inorder-preorder-and-postorder/).

When i do a print(bst.InOrder()) it return None?

I am currently trying to solve the xmas tree problem, with internal tree-like shape.

issue is with internal spacing, it supposed to be like: 1, 5, 7, 9. Instead it is 1, 3, 4, 5. I do not know, how to increment s loop by 2 in each loop turn.

I'm building a website with Vue.js and use PixiJS to dynamically draw a canvas with data that comes from a big json file. The canvas is generated as a component and used in a view.

Now the first time when I navigate to the view with the canvas, it all looks fine. But when I start navigating between views, the drawing is all messed up, the sprites are all there but it looks all out of place and messy. When I then refresh the page, the canvas looks fine again. Here is an image:

I'm not sure what the problem is here, but I feel like it's a combination of things. Maybe the 100k line json file I'm working with has something to do with it (the view also feels kind of slow when I interact with it)

This is kind of how my Vue component looks like:

I have a d3 chart that have both left and right paths/nodes. now what i'm trying to do is that on click of a node i want to append the same data ( same tree with left and right nodes ) and this new tree will be populated/centerd according to the clicked nodes x and y values, so i tried to add a new g with the x and y values i got from the object clicked.

like this

How can I make this tree's angle and depth to be random by using 'random number'?

In the below code JFrame is been used. The intent behind the question is to get the idea of randomizing the angles and the depth, which is passed in the paint method.

i'm new to d3 and i'm trying to render this d3 tree chart with left and right nodes. the initial tree render is working fine and i have added a toggle function that will make the children null and call the render method, but it's not working. please help.

I'm working on a D3 visualization that shows the parent and child relationship.

I'm able to visualize the data perfect when I've less number of children, but when the number of children is more, the child nodes get overlapped. how can I modify my chart so that all the nodes towards the left of the root (right) are visible? like having the nodes in a circular fashion around the root, having some nodes near to the root, and some far in some order. What would bee the best way to show it?

Here is my code.

I'm trying to build a tree using d3js. I'm having a 2 sided tree with a root in the center. I am showing parents towards the right of the root and showing children towards the left of the root. here is my code.

I'm trying to write a function that takes text file as input and turns it into the JSON tree format below so I can use it in my d3.js project.

The text file is really simple: Every line that starts with 'b' represents a bag and the following integer is the number of the bag. Each bag contains nodes.

So the first line is bag 1 with the nodes 1 and 2. The lines that does not contain b represent the links between the bags. So bag 1 points to bag 2 for example.

Sample input:
