Java Programming - Practice Recursion Problems

Recursion refers to define something in terms of itself. In this tutorial, we will solve difference recursion problems to get the better understand of how recursion works.
We will solve from easy problems and go to advance recursion problems.

1. Recursion of factorial.
2. Recursion of Fibonacci series.
3. Recursion of binary search
and other string, array recursion problems

Thanks for uploading this video. I was looking for the basic problems on recursion from yesterday to get started on dynamic programming. I could not find a single video which starts from the basic. Most of them are either at a high level, or just algo, or just theory or simply avoid explaining the basics. This video definitely helped me to get started on this topic of recursion.

it helps me a lot when i am stucked totally with recursion

[donrochuios]

this video was so helpful. could you do another set of problems involving strings and arrays?

[bebarshossny]

Really benefitted from this video
Especially pausing and doing the problem first then checking my answer
Thanks a lot great video

[nareshbanra]

Please show the dry run of each question , so that the logic will be cleared .

[pauloalencar]

this video was really helpfull to me, thanks a lot, now I can understand a little bit more about recursion.

[Daniel_CLopes]

Thank you for taking the time to do this great great video... Fantastic lesson about recursion!

[RobinsAustineMathews]

For base and power question, the base condition you have mentioned is incorrect. You should use if power==0, return 1 as the base condition. Else 2 to the power 0 which is 1 will throw an error in your code

Thank you! Your explanations are amazingly clear and the examples really help solidify the theory that we have learnt.

If you'd get a dollar every time you said "All right?"...)
Nice video anyway, just what I needed.

[fishaorod]

thank you so much sir. amazing video for cs students

[shinebright]

Thank you very much the video is very helpful even tho i wished you had some examples with array

[TRUTHFRCE]

Great video! Various exercises in one video, thank you very much.

Bro this video was Ok but try to put some advance (how recursion works inside (for loop )) with step by step process

[RahulKumar-tgzb]

sir plz tell me how can I write a java program using words
{J, O, K, E, R} to show it's all possible pattern and also count total no. of words formed.

@ 35:47 I feel like you overcomplicated that one:

if(n==0)
return 0;

if (n%10 == 5)
return 1 + count5(n/10);
else
return count5(n/10);

I am learning recursive functions in Haskell and I like the way to connect the same functions topic in both languages. I enjoyed your videos, I have to practice data Structures. Do you have apache Spark video materials, or Scala recursion topic? Kind regards.

[RedRebel]

Way too many ads - destroying what could be the best recursion video on youtube.

[devada]

For 8: This should be good enough right why bother about all those nested loops?

public static int countDigit5(int num) {
if(num < 5) {
return 0;
} else {
if(num%10 == 5) {
return 1 + countDigit5(num/10);
} else {
return countDigit5(num/10);
}
}
}
