this video and the paper 2 video gave me the power to cook stupendously in the exams and get an A i am eternally grateful 🙏🙏🙏
Too much for 1 lesson this video should've been in 2 lessons.
Thank You ❤❤❤
i love you
why is ur pfp a wojak?
Wish I did more on heuristics but other than that it was a good paper it’s been an honor S1perry saved my Cs revision🙏
whos watching after the exam
Thanks for saving my grade (again)
Like if ur cooked
Thank you for your service s1perry, the exam was not too bad tbh

You're welcome!
s1perry my glorious king THANK YOU ‼️‼️‼️ for potentially saving my cs grade
Just finished the exam what was that man in cooked 😭
26 min till exam am I cooked?
Exam is in 10 minutes make dua for me🙏
who’s watching right before the exam starts😭
Me 😭 (I'm not actually watching it)
who’s here 10 minutes before the exam on 2x
what’s a pseudocode, am i cooked?
51:37 isn’t top meant to be after stack top as it it adding one but then referencing it
I think top here is the pointer, not the next free space
So we add top by from the current top to the next free space ontop
@@Conquermindbodyandsoul isn’t the pointer already pointing to the next free space so u put ur data there and then u increase the pointer to show the next free space
In the exam they are gonna use pointers not top but if top is an item and highest on the stack them it kind of works as a base model
Are we cooking today?????
hell yeah brother
Yes sirr
YEAH
good luck to everyone taking paper 2 on the 18th today :)
I’m watching this an hour before the exam cramming is wild
