I thought I was at least decent in recursion basics before watching these videos... even after watching so many videos on recursion ... learned a lot ... thanks Bhaiya ❤
Horizontal approach was length but you nailed it.. Because till now I have seen ppl writing vertical and for me it was tough to trace but since you taught horizontal approach its way easy for me to understand vertical onwards Thanks for efforts Striver 🙂

Understood. Today is November 29th, 2024 and i have just completed watching this video. I will come here periodically to update my status and my offers! Wish me luck!
i understood how this works.. But I want to know how could I have an intuition to use this multiple recursion for my problem..How could I know whether my problem requires multiple recursions or not?... This functional recursion is like backtracking. We have to think in reverse order.. Is human brain that much capable?...
Thankyou striver for making such an amazing video. Now, I can easily write multiple recursive function algorithm for most of the any AP series with the help of this tutorial video.
I was able to do recursion problem from before too but didn't know the internal working of it but this video helped me understand that too. Thank you sir.
Thankyou STRIVER, I have made a directory of your name and I have folders in that of different playlist you have explained. I have understood Multiple Recursion Calls.
I just love your videos. They deserve a lot more ! I just like and then only start seeing the video as Im sure there arent any chances that I dont understand it...
Thank u so much sir🙂 This video has explained me multiple recursion calls very clearly...Friends explained multiple times but I didn't have a clarity. Finally i understood wt is happening 🥲
Python Solutions for above questions: Fibonacci Series: iterative approach for first n series n = 5 first = 0 second = 1 for i in range(n): print(first) temp = first first = second second = temp + second // iterative approach for nth term def fibo(n): first, second= 0,1 if n == 0 : print(first) elif n == 1: print(second) for i in range(2,n+1): result = first + second first = second second = result print(result) n = 6 fibo(n) // def fib(n, dp=[0, 1]): for i in range(len(dp), n + 1): dp += [dp[i - 1] + dp[i - 2]] return dp[n] n = 6 print(fib(n,dp=[0,1])) // fib = [0,1] n = 7 for i in range(2,n+1): fibo = fib[i-1] + fib[i-2] fib.append(fibo) print(fib) # n series (loop should be 2, n) print(fib[n]) // # nth term Recursion approach for nth term def fibo(n): if n
i did this -- each and every time you give a question and i try to solve it my self and see whether i could or not! and this really helped, and before starting the video again i say in the comment :) sometime i see i use more variables and i learn that the question could be done using less variables. thanks for the series, btw i was going to learn dp but sir u said to first watch the recursing series at least 10 lectures, and here i am 😂 int fib(int n){ if(n==1) return 0; else if(n==2) return 1; else return fib(n-1) + fib(n-2);
striver you are simply great.but there is a simple math formula to get 'n ' th fibonacci number which is called Binet's formula here we go------f(n)=(1+root symbool 5)^n - (1-root symbol 5)^n/2^n root symbol 5
I wanted to take a moment to express my sincere appreciation for your invaluable assistance. You've truly been a guiding light in helping me connect the dots that seemed elusive before.
Thank you, can you or anyone in here tell me in which of your videos do you explain a recursive call INSIDE a loop(for loops in particular)? I somehow get lost in tracing the call, really appreciate your work!
hi striver, was testing time taken for each, and got to know that recursion is very very slower , compare to while, where exactly this recursion is used in real life problems? check output below: 46 while ans:1836311903 Time measured for while: 0.00083 seconds. recussive ans:1836311903 Time measured for recursion: 11.47690 seconds.
I was struggling understanding multiple recursion , I have tried python tutor, turbo c what not, but failed understanding it . Thank you for this video
Thank you for your effort in teaching recursion. I just have one question: since 0 is the first number in the Fibonacci series, shouldn’t f(1) return 0?
I was indecisive with recursion for last 2 years.... Finally, finally i would say....i can understand recursion
❤
💯
too good bro, learning 1st sem topic in 6th sem, but its never too late when people like you are there by our side

thank you striver for explaining the multiple recursion so well....blessed that i came to know about your channel
Ah, very good, dang, thanks!!! I was confused on the order. This is excellent and makes perfect sense

But I want to know how could I have an intuition to use this multiple recursion for my problem..How could I know whether my problem requires multiple recursions or not?...

U can use multiple recursion in ds trees and graph topcs
This is the best recursion video I have ever watched ; thank you so much for clearing my doubt
You Rock Man. I am not commented in any video till now this is the first video where i can,t go without comment. Amazing Explaination.

it was just like roting!
without knowing internal working how can you do problems?(by remembering???)

It is available in his sheet
thank you for the wonderful class!

i wish i saw ur vidoes earlier! you're really cool. will share the word
nice explanation no one explained recursion in such a good way on u tube
its an amazing playlist for recursion
We can become an educator after watching striver's video's
hi striver, was testing time taken for each,
and got to know that recursion is very very slower , compare to while,
where exactly this recursion is used in real life problems?
check output below:
46
while ans:1836311903
Time measured for while: 0.00083 seconds.
recussive ans:1836311903
Time measured for recursion: 11.47690 seconds.
Time complexity is golden ratio of n .Its not O(2^n).the complexity of fibonacci is O(Fn) = O(ϕn). This is approximately O(1.618n).
You make this shit a cake bro...well done!...
Amazing , Super explanation
Understood, awesome explanations provided by you. Have watched a most off DP series they're all, each one of them exceptional. Thank you ffor this!!
understood. Thanks for your hard work.
thankyou Striver bro thankyou so much❤❤

hey Raj bhaiya, what's about tail and non tail recursion. you haven't explained any code on that
Time complexity is 2n-1 for this particular problem
best instructor
thank you dude this what i exactly needed
Godlevel explanation ❤
Thank you for your effort in teaching recursion. I just have one question: since 0 is the first number in the Fibonacci series, shouldn’t f(1) return 0?
#include
using namespace std;
int fib(int n)
{
if(n==0||n==1)
return n;
return fib(n-1)+fib(n-2);
}
