Hi - you will get the most benefit by working through the problem yourself which is why folks are hesitant to “do it for you”, as you won’t learn meaningfully that way.
Have you tried putting a break point in the code and using the debugger? (You can use the code “self halt.” If you can’t figure out breakpoints (but I’m sure you can find docs on the debugger). Then see what the state of things are. Step into code and see what it’s doing. You can also evaluate expressions and get results to check things (if you can’t figure that out - assign some temp variables). This is how you will learn how to help yourself, and it will make you more productive in the long run.
