This was very helpful thank you!
Thank you you helped me a lot today's my computer paper
Hello, please can you say if you need the arrows for the sub process thing at the end. Cheers
This channel should be recognised more for real
Legend!
thank you ! your video means a lot
dont think my textbooks are hard carrying me anymore
learning more in a 7 minute video than i am in 6 hrs of computer science lessons😅
Very useful, even today!!
thank you 😃very helpful
Actually very helful. Thanks
Cheers👌
Got the exam tmrw it’s 1:31 am - going for the grade 9 💯💯
so its very similar to bubble sort?
amazn
nooooooooooooooooooooooooo theres no videos on 2.3.2 and i dont know anything and make exam is tommorow
SO HELPFUL! Exam on Tuesday so has helped a lot thanks!
how was it?
@@viperdio69420 it went alr. thanks for asking
watching this 2 days before the exam, thanks to a terrible teacher we were never able to learn the programming skills required for paper 2. thank you for giving me a chance to do well in paper 2 with your videos!
imma clap u
Second that but with 12 hours before the exam🤑
I love you
Really underrated, your videos help a ton! cheers
thank you so much, exams tomorow and you are actually saving my grades
really helpful thanks 👍
sheesh
underated channel bro.this helped me so much
cold video
Only Person Who explained Networks properly 🔥
Got computer science tomorrow watching all your videos their very helpful
Lovley Man, I've been watching these since yr 10 and until todas, the day before my exam so Thanks for it ALL!
u vs me ong
Nice video great explanation
I really love your explanations, reminds me of StampyLongNose Minecraft letsplays
Your saving me from failing from my computing exam .. keep it up ✨🙂
this channel is rather helpful because i have missed over a YEAR of school, all because I was hit by a car, and of course my stupid school isn't letting me come back despite the fact my brain injury is almost completely gone! at this point my dad's considering a school that will be better for me lol
thanks so much for this information, as a marketer working in the IT industry this is really useful 🙏
shit video dont watch
fridges are an example of an embedded sytem tho..
Well,one dimentional is easy but it would be great to do a video on two dimentional arrays in pseocode as well.im really having difficulties with it .
❤thank you
Thanks ur videos r good
Thank you so much for the video! I love how you keep you explanations short and concise, makes understanding a less tedious thing to do!
Sir shouldn't we use a back arrow for assignment<----
flippin quality sir , thanks , im aiming for an 8
Very helpful. Thanks!
Thank you
2:09 deffo didnt guess that loll thought it js doubles it each time 🤦🏻♀
wait hold on it does double? wth y did i think for the 3rd shift it's x6 then..
@@KM07920is that wrong help idk
@@btluvz2920 whats in the vid is right idk what i was on abt loll
outer wilds is a goated game
arrays is the only reason i learnt psuedo code rather than doing my tests in python like i was orignally gonna do
well for me i learnt python instead of pseudo code cuz i find it easier
@@articticcblu imo they’re easier in pseudocode but each to their own
Flow Control Structure - (algorithm) Control Structures Sequences, selections, and iterations. No loop terminology. Programming constructs. iteration is a form of feedback. Iteration is either conditioned controlled (while) or count controlled (for).
bro explained this better than my computer science teacher
bro my computer science teacher didnt even tell us how to code and we have exams
@@zeke8953 crazy☠️
Amazing videos
yeah but how does servers have the datas? are they being saved from previous requests? and how are they getting stored?
basc the peer will send the data to server. its just stored in a databas
helped a lot g
