How to Understand Any Recursive Code

How can you possibly learn how to use recursion effectively if you don't understand recursive code?

The short answer is that you can't!

One of the most important skills to master if you want to become truly great at recursion is learning how to trace through recursive code. In this video I show you how to do exactly that.

You lost me at the combinations part...

Thanks for making it so clear. A lot of videos have shown that both (n-1) + (n-2) gets put to the stack in the first occurrence which is very confusing. But this video make it clear that (n-1) gets called first all the way till it reaches the return statement.

Recursion has always confused me and this video finally made it click! Thank you so much!!

[vermilinguas]

I spent all the day in trying to figure out what double recursive call is. Then I found your video and all the things became clear ;) Thanks!

Perfect. "How to recurse on Find all combination" is exactly what I'm looking for!

don't remember how long I have been searching for such a tutorial. Thanks, men.

[ghazanfarabbas]

Super beautiful lecture I ever seen about recursion. This tutor definitely deserve, millions likes.

one of the best recurrsive explanation i have had in my life thankyou, so much

[xyzabc]

Thanks for providing that computerised chart at the end. That helped a lot to make things clearer.

[xXTomeloXx]

This just made a problem I was trying to solve with graphs more understandable! Thanks

[samyuktharajkumaran]

The most lucid explanation of recursion that is broken down into understanding it as chunks. Instead of groups of wholes which is sometimes difficult for even intermediate programmers to follow.

[nickwu]

this is exactly the way I expected to see an answer to the order of operation of a recursion, thank you! great !

That first part is the best explanation I've seen to date

[mohammedfaraaz]

Thanks man!

For people not able to understand the combination problem, I would suggest first understand the code, next draw a tree on a paper and then solve it on your own. This will help you understand recursion better. Good Luck ;)

[m.khanmohamadi]

i have already spent lots of time for understanding recursive function then when i found this i told myself (wow).
thanks bro ...

[alvarodelgadoclavero]

Thanks to you I could unserstand how itertools work in python and make my own functions for combinations without it. Thanks from Spain

[manprabeshboruah]

The perfect video what I was looking for. Thanks sir!

[Artificial_Intelligence_AI]

This is easily the best video of recursion that you can find in the internet. All problems brilliantly explained step by step, for me this deserves more views, I have no doubt about that.

[geekyprogrammer]

Wooaw! You really deserve more viewers for this!

[pastafarian]

Thanks for making such a difficult topic so easy.
