What did everyone do for the last question for fullStop?

After creating the procedure, opening the file etc I used a for loop and a while loop inside of that to check the spaces. Did anyone else do that?

For the question about deQueue, could you just write the pseudocode out and explain it ?

When it said to write out the insertion sort and bubble sort did you just perform the sort?

Performed the sort yes except for the second half of the bubble sort one that asked for an algorithm

It was an ‘explain’ question so I wrote about checking that the queue wasn’t full using the pointers, then incrementing the end pointer by one and appending the item to the position of the end pointer

Hey guys if its not too much to ask can someone just give me a brief summary of the precise topics that came up in Paper 1 and 2 as I am an A Level student who has his first H446/01 exam on the 3rd. If you can list it out in bullet points I'd be really grateful.

Well, I wrote the pseudocode out and wrote annotations for each part. Explained each point.

Maybe it was I just forgot, I basically said check if it's full and then decrement rear
and the pseudocode:
PROCEDURE AddToQueue (item):
IF ((front-rear) + 1) == max THEN
queueFull = True
ELSE
rear = rear - 1
queue[rear] = item
ENDIF
ENDPROCEDURE
