Thank you for the help but I have sooooo many errors, your Queue gets full even if I use the remove_from_queue() function, the stack didn't work because you used = instead of == , for the if statements and the queue couldn't even load because you didn't put global QueuePointers etc etc inside the functions.
For anyone who has trouble getting the queue to work, I tried doing a paper 4 mock and tried implementing the Queue system showed here but I got the comment from my teacher as "overly complicated" : def add(newItem): global QBack, items if items < QSize: QBack += 1 if QBack > QSize - 1: # MINUS 1 IS IMPORTANT SO YOU ARENT OUT OF INDEX or I think you can use >= QBack = 0 Q[QBack] = newItem items += 1 else: print("Queue is full cannot add") def remove(): global Q global QBack, items, QFront if items > 0: Q[QFront] = None QFront += 1 items -= 1 else: print("Nothing to remove") QFront = 0 QBack = -1 QFront = 0 QBack = -1 items = 0 QSize = 5 Q = [None] * QSize add("Venti") add("my") add("pookie") add("bear") add("I love") add("Lord Barbatos") print(Q) remove() remove() remove() remove() remove() add("Anemo Archon") add("Ga Ming is pretty cool and relatable") add("I want dim sum") add("Liyue Harbour") add("WOAHH ITS ZHONGLI OH MY GOD HAIIIII") add("this should not get added") print(Q) This may not pass for the pseducode questions in Paper 3 because you have to learn it the way the Cambridge book suggests and this video is close to the pseudocode from the book but in python, but at least this worked for me.
Hey everyone, you can purchase the slides that I use here 🏬😉:

Thank you for watching and supporting!
Your efforts are greatly appreciated. Kindly make a Video about attempting Paper-4.
Hi sir, really helpful video. I had a question, all these programs are in python syntax right?

Hello! I have checked the stack and queue code, they are fine 😅 perhaps you could let me know which timing did the problem occur? Thanks!

Algorithms is a paper 4 topic which you can do in multiple coding systems python,pesudocode,java etc... but thanks for the added info!
