What Is Recursion - Recursion Explained In 3 Minutes

Maybe the point is minor. But recursive functions call copies of themselves. If a recursive function ca;;ed itself instead of a copy of itself, its definition would be circular.

Who's here in 2017?

So useful thanks.

Thank you!! I really like the examples, very easy to understand. 😀

Recursion has been breaking my brain for ages but I feel like I finally kinda got it, I just needed it explained to me like I'm a child to be honest

These visuals were perfect!

the if statement within this function, the second statement should have a for or else condition no? it just says return?

Recursion is nothing but when a function calls itself and forms a process of chaining occurs this is called recursion

Love the reverseString example, I think this was exactly what I needed.

Beautifully explained!

Very clear video!
For the people that don't get it.
Recursion is where you make a new function and use that function in the new function.
Best I can give you

thank you so much for explaining this and simple terms and getting to the point. I've watched so many videos on recursion and all of them are spending more time teaching me the Fibonacci sequence than how to actually do recursion and what it is. Thanks again I understand it now because of you 👍🏽

the best expalantion so far !!!!

this confused me even more ;-;

3 minutes of utter confusion! I still have no idea what recursion is!

I didn't understand this but I did enjoy watching this video. Programming will start to click in my brain sooner or later.

When I run this code I get an error "RangeError: Maximum call stack size exceeded"
meaning you have created an infinite loop?

Not all Algorithms can be writen iteratively look at the ackermanfunction
def ack(m,n):

ans = 0

if m==0:
ans = n+1
elif n==0:
ans = ack(m-1,1)
else:
ans = ack(m-1,ack(m, n-1))
return ans

Nice, Light Explanation on Recursion. Well done.

Whe. To use recursion over iteration?

u r d best explainer ever for recursion with example ..

do more videos.. very easy to understand

Great concise video!

what is font use in video? thank bro

very nice

Nice explainer, thanks!
