would have loved it, if you made the video in chapters.

At 18:51, could you explain why you put the double brackets around it, wouldn't it also work if you wrote: instead of

Another question, if you check the mark scheme for this question, you'll find that the line is actually so I am not understanding the significance of str() because the program works fine without converting to string

[hello-jzsg]

pointers are not updated?? even the markscheme updates the pointer wrong...

Please make other videos on paper 4. It really helps for revision

[Kellyoliviq]

hi if im doing the regular ocr not CAIE can i still use your videos to revise and get notes or is the content different?

Passing varialbes as parameter would make it a local variable within the scope of the function. Does that mean once you call AddNode, the variables wont actually change the value?

I ask you: why node list data from paper change on code:
From this:

linkedList = [node(1, 1), node(5, 4), node(6, 7), node(7, -1), node(2, 2), node(0, 6),
node(0, 8), node(56, 3), node(0, 9), node(0, -1)]

To this:

linkedList = [node(1, 1), node(5, 4), node(6, 7), node(7, -1), node(2, 2), node(-1, 6),
node(-1, 7), node(56, 3), node(-1, 9), node(-1, -1)]

Why some value from 0 to -1?
