Hi
So true man
Fun4 = 7 + fun2
Fun2 = 7 + fun0
Fun0 = 1
Fun4 = 7+7+1 = 15
Bro its wrong
@@muhibosmani4838 No, he is write output is 15
It's right
What I'm wondering is the 7+7
Fun 4 runs false
Fun 2 runs false
Fun 0 is true so it returns 1
Just so I'm clear that would be 7 from the first false, 7 from the second false, and one from the true making 15????
@@davidecheagaray2256 no, when n=0 then it returns back to the caller, which is fun(2)...then fun(2) becomes 1. 7+1=8 and return 8 returns back to the caller which is fun(4)...7+8 is 15 and that is the end and the output :)
Generally, I only concern with my own business, BUT after watching your videos duh, I couldn't stop myself from commenting and appreciating you guys. You have been doing such a fantastic job; your channel must deserve appreciation and recognition from all over the globe. Thank you very much for providing such quality content.
Am a kind of person who was afraid of coding, but after watching Neso academys course, i feel confident enough to do programming.
Its really really the best tutorial of C :)
Neso academy..... Doing very appreciating effort to learn us computer science..... Let me say value of effort..... This means alot to me..... My exams are coming.... M learning toc tutorial from NA.... Guys very appreciating tutorials video..... Thanks alot..... We should keep support neso.... Love you sir..... 😃
I've been struggling with the concept of recursion for the past two days. But after seeing this video, I can say that I have learned it very easily and quickly. Thank you sir for the great explanation.
Output - 15
I was scared about this topic, and I wasn't able to understand it.
You made it so easy. Thanks a lot NesoAcademy.
I have gone through a lot of youtube videos, but your tutoring in c is the best. Keep up the goodwork
Ans 15
fun(4)
return 7+fun(2)//15
return 7+fun(0)//8
return 1//1
Output - 15
yes its 15
fun
@34. Pragati S fun(2) is replaced by their previous return value 8..so it will return 7+8
How return 7+fun(2) = 15 can you elaborate
@@techtipsinkannada2.035 fun(2)=8
Return 7.
Return 7 + fun(2)
7+8
=15
@@techtipsinkannada2.035
here fun(4) = return 7 + fun(2) //7+8
where fun(2)=return 7 + fun (0) //7+1
where fun (0) = return 1 // at which the "if" condition is true
Was learning recursion last night. What a pleasant surprise. Great video as always!
OMFG I FINALLY understood the recursion after browsing 17 different videos and articles, this explanation finally hit it home. It's not actively changing the function, it's merely putting the old calclation on hold until it can figure out all of thew parameters for it. Thank you so much!
I had a very hard time wrapping my head around recursion, definitely not after this video.
Thank you sir!
Thanks a lot for explaining this topic in such a simple way. When I first learnt recursive functions, I couldnt understand it but now i do, because of you.
Neso academy you guys are doing awesome... I am fresher in CSE and recursion for fresher is tough.. but you guys mske it interesting and easy.. Go on!!🤘
THE BEST EXPLANATION OF RECURSION TOPIC ON WHOLE UA-cam...RIGHT NOW!!!!WITH BEST ILLUSTRATION OF STACK DIAGRAM ...
THANKS SIR !🤗😇🙌🙌🙌🙌🙌
I was having a hard time understanding this lesson, I just couldn’t understand even I kept on watching and reading. But then I saw this, it help me visualize everything. Thank you so muchh! Your tutorial’s the best :>>
True
The fact that you wear a face mask to take a picture of yourself, is proof for insufficient IQ.
Maybe you should learn stuff that's more suitable to your abilities, like mopping floors or bagging groceries at Walmart.
It will save you a lot of frustration.
@@DaRza17 bruh what
@@sathish5470 What part of my comment didn't you understand?
I meant what I said!
@@DaRza17 why are you rude ?
Thank you for the video.
It helped me understand the recursive function used in Towers of Hanoi!
Owowwwwwwww!!! I get it now! Thank you soooooo much! First time saw your channel and you made me understand recursion( which made my head spin around) in one go. I subscribed right away. Thanksalot👍
now i can understand the the relationship between the caller and the return. it was not clear, thank you Sir! :)
before i found this channel i coud not see how i was going to pas my exsam i december., but now i i my hope back. even throu i have used one day to just remeber all of what he is explaining the same way, i gues i have underston allot in c programing for my tasks that i have to deliver.
Forget Coaching Institutions... Forget Tutorials....
The Content U will Get From UA-cam and Channels like *NESO ACADEMY* are Mind Boggling...❤️❤️
Thank you Neso Académie... I don't want Programming Certificates by Going to Coaching class.. I want pure Knowledge.. And u supplying it FREE OF COST.! for us. Is only an act of Kindness and sharing knowledge. 😊😊🙏❤️❤️❤️❤️..
May ur Channel live for Ages....
This channel is amazing. clear speaking and good graphical representation
Thanks for this. I was stuck at the recursion example in CS50's lecture 3. This expounded perfectly.
Finally I understand recursion & every aspect of it. Thank you..!!!
Finally understood recursion , thank you man. I watched different videos on this topic and managed to get bits and pieces about recursion from each of them. But when I finally watched your video, everything just clicked.
so fkn true
In Future A Lot Innovations would be due to this channel...
This is the best channel to learn C programming language. Just before I was struggling in trying to learn and understand how to make linked lists, I learned just by watching those videos.
God bless you man!!
I was looking for this kind of explanation.
many many thanks👍👍👍
Great full to you guys done awesome job 😍😍😍 kudos to the expliner and the best slide maker 😎😎 looking forward many more videos on cpp and c
c) 15 , n=4 return 7+fun(2)
n=2 ,return 7+fun(0)
n=0, return 1
7+7+1=15
Literally, I have seen many videos, but you people have explained the best , thanks..
it's really fascinating how good you explain and how clear u make concepts,
Thank you very very much. You are just awesome and made my day. It was so easy to understand the way how i learnt recursion. Along with that it helped me to visualise the stack as well :)
Simplified and thorough. Thank you so much!
Good job of demonstrating method 2!! Really makes recursion simpler to solve!
Thanks to all of you for this channel,I really learned a lot from here🙏
I love this tutorial , it's way better than payed courses on some other sites
*paid
*paed
Yes bro
Thank you Neso Academy, you helped me to understand this concept
wow...thank you...struggled to understand recursion...so I gave up initially.....some time later, I knew it was something I needed to understand...now... thanks to you...I now get it, thank you again.
first of all thanks so much , I couldn't understand recursion last 3 days after learn recursion but after some search . I am here and understand actually how recursion work step by step . again thanks a lot brother.
Good explanation.
Good visuals.
Easy to understand.
Thank you very much.
wow!!! what an excellent explanation good job!
I have been able to solve recursive problems in C because of the approach taught in this video, Thank you so much.
my mind is blown. crazy stuff! thanks for sharing!
Obrigado, pela aula. Excelente explicação 🙏🏻
thank you so much neso academy i have understand this actual logic of recursion after 2 years😀😀🤣🤣😅😅
This is the advantage of learning from a GATE aspirant..
He will take u to the depths of the topic 🙏🙏🙏🙏
i cant believe recursion is so easy after i saw the video...very good explanation...thank u so much sir
result= 15
return 7 + fun(2) =7+8 = 15
return 7+ fun(0) = 7+1 =8
return 1
I dont understand why 7+8
correct
God bless this channel. Thank you sir :)
Best explanation of working of recursion yet on UA-cam 👍👍
Thanks sir ...such a excellent explaination sir , I never understand recursion before...and each and every concepts that you explain are very easy to understand...
I love that sentence "recursion is not the science of rocket", we always say this sentence in Algeria to express simplicity of something hhhhhhh
In india we also say , "There is no rocket science".
1 2 3 viva algerie ههههههه
I can understand the topic literally after 2 months -,- THANKUUU
true!
this is the best possible way in which recursion could've been taught grateful to find this video thanks a lot!!!
I guess this is the best explanation of recursion so far, even cs50 couldn't explain it better !
You guys are gem.The way of teaching is amazing ,even though I thought I knew recursion but after coming here I came to know that I had understood recursion in a wrong way espicially that stack thing was amazing ...May your channel grow and grow and grow.....Gud luck..
Option c. 15
fun(4) -> return 7+fun(2) -> return 7+fun(0) ->return 1
fun(2) = 7+1 = 8
fun (4) = 7+8=15
output = 15
How you get 1 and 8
Ok I did understood
tq brother
the work should be appriciated.well done neso academy the content u r providing is very helpful for us.thank u very much.
This is the first video I have ever watched from your channel on one of the topics that has eluded me the most in programming. In 7 minutes you have explained something that for years I haven't been able to comprehend fully. I don't know how to thank you but one day I might make a contribution to some open source program and I will credit you if I use recursiveness. I absolutely loved the way you showed it so clearly with the stack diagram. When you said it's not rocket science you would not believe my huge smile at that moment because that's exactly how I felt! Thank you to the narrator and everyone involved in this channel!!!
Thank you sir..god bless you❤..
THIS IS THE BEST CHANNEL FOR LEARNING
ALSO ANS IS 15
This is by far the best video about recursion on youtube.

Thank you so much sir for making this super simple to understand video ..🙌💟
Now i am able to solve recursion problems !
Thank you so much for such good content you always there for me especially in fundamentals of digital electronics.
Take love neso academy.❤️
God level explanation Thankyou sir
OMG dude you help to understand recursion better my professor! I have watched CS DOJO, Abdul youtubers and you are the best. subbed!
one of the best recursion video on youtube
Your way of teaching can help me a lot to understand the complex topic in a easier way
The way you teaching is awesome. And it's crystal clear!
Thanks a lot!!!

fun(2) = 7+1
7+7+1 = 15
How to calculate value of function 2?
@@beingaware43
fun(2)=7+fun(2-2)=7+fun(0)
7+1
fun(2)=8
Here fun(0) returning value 1, thats why fun(2) returns 8.
@@praveenpatel9972 1st call fun(4) =7+fun(4-2) =7+fun(2)

This is unbelievably helpful...
... Right?
Right!
Ans: 15
I didn't know what recursion was, I watched this video, and I instantly understand it, a really good video.
Best recursion video i've seen. Congrats!
F*CKKKKK. finally, THANKS SO MUCH MAAAAAN!

SOLUTION :=
(SEE FROM BOTTOM TO TOP)
7+fun(2) // 7+8
then
7+fun(0) // 7+1
so
. ' . fun(0)=1
That Method 2 man..!!
I don't know why I have been struggling to understand this simple thing until now
Best Explaination I Have Ever Heard
you and your drawings are a blessing to us beginner programmers
15 is the output 🤟
Fun 4=return 7+fun2
Fun 2=return 7+fun 0
Fun 0= 1
Fun 4= return 7+return 7 + fun 0 (7+7+1=15)
15 is the answer. please tell me I am right or wrong.
yes 🙌 some relief to me after understanding recursion and required practise .
Super sir I have confusion of recursion since my B.tech 1st year now I am in final year and solved my confusion TQ you cheers : )
Hi bro
15 is the answer
ans c) 15
fun (4)
return 7+fun (2)
return 7+fun (0)
return 1
then
return 1
go to
return 7+1
go to
return 7+7+1
go to
fun (4) at main
giving 15 as answer
Thank you so much, this is a great help for me, this simple topic help me to understand recursion, thank you and wish you help other people
So , aptly put Sirji! Thank You so much for your hard work
fun(4)
|
return 7 + fun(2) // 15 [value of fun(4)]
|
return 7 + fun(0) // 8 [value of fun(2)]
|
return 1 // value of fun(0)
So the final answer is 15.
Ur answer was pretty helpful😢👍
u sometimes sound like barjirao mastani wala ranveer singh
Thank you so much sir for making such value adding videos.....for free.❤❤i have respect for you from the bottom of my 💖💖
