Orange | Java web course selection system using Oracle

I have this component that contains a card and inside this card there are elements and I want to separate them through a vertical line and the problem is that the vertical line does not work.

I create a Pentest tool for educational purposes, so the old version was written using python 2, then I convert it to python 3 and when I try to run the main file pxxtf.py I got multiple errors, I correct most of them but for this one about Circular Import, I try multiple fixes from forums and StackOverFlow and nothing work with me.

When I try to run the main script :

I want to drag and drop those 3 shapes into mxgraph canvas (which is the black area).

Note: I want to fully preserve the drag element on the canvas, including shape, size, color, text, etc.

I don't know whether insertVertex does it work. Dragging the orange,red or other box in to the dark area currently does not work.

I have this code inside which I'm calling "makeView" function that returns a View, and in the makeView function I'm incrementing the variable "id" and passing it to the View, but when I do this it shows this error

"Updating a preview from SongsList_Previews in SongBook.app (2935) took more than 5 seconds."

And surprisingly when I comment out the line "self.id += 1" everything works. I'm new to SwiftUI, so forgive me if I left out some information.

I have a string with words that sometimes have after them ,, ;, ., :. It is possible to have one or more spaces after these punctuation characters. I need to extract just the existent words.

For example, from:

I succeeded to solve this using "naive" solution checking for each node the longest path including this node but was told there is a better solution.

I am looking for help with how to solve this problem efficiently and how to approach similar problems (tips or thinking method will be appreciated)

Say I have a tree where each node is orange or white. I need to write an algorithm to get the length of the longest "good" path

a "good" path is a path that starts at a white node, climbs up 0 or more white nodes and then go down 0 or more orange nodes

given the next tree as an example

the algorithm should return 4 because the longest path starts at 18 and ends with 15

I want to display recyclerview items after every 10 seconds. For instance, I have 8 items in my arraylist. Initially I want to display 3 items, then after waiting for 10 seconds first three visible items will disappear and next 3 items will show. how to achieve it ?

My table looks like this

I was creating a todo's list with JS. I have attached the code snippet for the same. I Have three hard coded todos in html and with each todo there are two buttons('x' to remove the todo 'y' to mark it as done) associated. Now for this hard coded todos everything is working fine. Now, to add a new todo I have this tag where todo text is entered and after clicking enter I am embedding them to html using innerHTML, while embedding the dynamically added todos are visible in DOM. But The problem is that the buttons('x' and 'y') associated with the todo is not working as expected. Further I tried to debug my problem and I found out that the buttons('x' and 'y') that are not getting selected. I could not understand why is this happening. Any help will be highly appreciated.
