Flow of Program - Flowcharts & Pseudocode

In this video, we discuss the flow of the program. Giving you insights about how to visualise your algorithms using flowcharts and turn them into pseudocode.

We cover concepts like if conditions, loops, and also learn how to find whether a number is prime or not in an efficient way.

Others: Let's binge watch Netflix
Programmers: Let's binge watch *Kunal Kushwaha*

Everything is Temporary, but "Hey Kunal!" is permanent XD

[ayushmondal]

this man is just on fire right now...🔥🔥🔥

I have never during my hunt for “good programming courses” come across such playlist which I can binge watch literally lying in my bed, yet not falling asleep or feeling bored. Learning from you is interesting. Thanking you for all your efforts. God bless you! :)

Although I know this basic, when you TEACH, learning again feels exciting !!! I am 52 by the way now!

Just in case, if anyone finds the final square root optization at 24:51 a bit confusing, I believe what he was trying to convey was, if (c*c) 4<36, and if (c) 2 [and not c*c, which is 4] divides 36 as it's written in the pseudo code. Added this for the sake of beginners trying to understand. As always, the video and the way Kunal explains is Amazing! Can't wait to get started with Java and more fun stuff!🤩🥳🥳

This is literally a golden video, u just need common sense to solve these type of problems, it's the CONCEPT, now I understand why programmers say language doesn't really matter. ❤️❤️🔥🔥🔥

If I had the power to give your videos Million likes, I would have done without a second thought.

Although I know this basics, but when you TEACH, learning again feels exciting ✨

[manavshah]

I know all the basic stuff but still I love to watch Kunal teaching.. ❤️🤩
Great work.. 🙌🏻🙌🏻

[rahulmanipal]

This series is going to be the life saviour for many of us!! Thanks buddy!! Awesome 🔥🔥🔥

[wecodetogether_]

Completed this today on 19/08/23, will stay consistent for the whole series. Thanks for the content.

[ritumansata]

after watching your videos, i feel like nahi kabhi history me aisa teacher aaya hai aur na kabhi future me aayega....just another levell, no words...✌✌

[ashwinharsha]

Just today I was thinking about learn the flow charts 😂
Kunal, You are dope 🔥👀😂
This is really helpful ❤️ we support you 🌠 keep on doing the good work 🔥

[p.d]

For anyone who is having issue dealing with the prime number question, here is how I understood it
Let's take a large prime number 4397, now if you take the original code which we used in question 3, what that code will do is, start dividing the number by 2, then divide the number by 3 then divide by 4 and so on till 4397, to optimise this what kunal did was he saw that the pattern repeats midway (like if we check for 2 then we need not check for 18 (in case of 36)because both 2*18 and 18*2 are the same things)and wrote a code such that as soon as the computer hits that midway it stops

Wrote this since i had a little bit of confusion at first but later after thinking for a while i got it...

[ѕнвнм]

Imagine how he managing stuffs for free only for us. .. ❤️❤️

[saketbarnawal]

He is a real talented person and providing his knowledge to the students. Great Contribution bro.

[soujanyad]

Hey I'm happy that 2 videos got uploaded on the same day. But we don't want our mentors to overwork themselves.

[orio]

I have started seeing your playlist bro and I am from Bangladesh. Loving your teaching method and explanation. Hope you will be always there for the international community. Please upload new videos in the playlist soon

[Abhijeetsingh-gcbq]

He knows magic his long videos are ending like it was only 5min video it feeling very blessed to have a mentor like him love u Kunal❤
