Coding Interview Question : Factorial Of A Large Number 

Sir, I am from Bangladesh. I have been getting stuck in finding factorial of large number since long time . Thank you very much for this tutorial !

This explanation gave me motivation to quit Coding. I am done printf("Bye World");

My GATE instructor told he used linked list to solve this but didnt have time to cover the code. Thanks for the wonderful explanation.

nice explanation suggestion : [len--] wasnt needed and it would be just while(len--) { cout

20 72 😂 It was funny 😂

My brain be like ...lets use python.

Wow..... It is most neat solution I've seen so far. You are great at teaching.... Totally nailed it

This a was a nice solution bro .. thank you for this .. keep them coming :)

In while(num!=0) loop, Why are we doing num = num/10; Can we simply make it num=0; Because num is never going to be greater than 10 Please explain?

Nice Explanation bro All youtuber who are doing this video are only writing the code not explaining anything.Thanks for that

YOU are great man. understood in one go Excellent, Outstanding love you

Finally I got solution for it. Thank You.

Bhaiya, your explanation is really awesome. The icing on the cake is your English you were too good. just tell me, if I work hard will I be able to speak English like you confidently

brilliant... enjoyed seeing you troubleshoot at the end.

Your explanation was vague at its best. You confused me more.

Thanks bro U helped me clear my doubts. Your explaining skills are really nice , even though I can only code in C language I totally understood you.

Thank you, very well explained solution.

you explained it well but the approach was unthinkable,how can smbdy thin this,probably would have 2 cramb this

lagta h 5 baar aur dekhna padega

best explanation for this question, thanks !

Very sweet

You are really good at explaining! thanks a lot

Well if we use python we can do it with same old recursion technique also.

Bahut mast kaam karta hai tum Bhai 😄😄

Pro explanation bro🔥🔥🔥

I got this question in my interview and first I stuck but taking some time and hint I am able to crack it.

but why are we storing the answer in reverse manner?

Bhai tu bhagwaan h 😭😭😭 Mene 2 hrs waste kr die the iss uestion pe

Thanks man.Perfectlyu understood...

Amazing explanation!!!!

wow bro u have showed me a way to think a problem thanks bro...

Loved Your Explanation....Thanks!!!

Thanks Manh

You explained so well buddy ! Thankyou :)

If u explain the login by dry run it with pen and paper then it would be better for most of the learners rather than just telling the code ...Thankyou

👌👌👌

well explained, all are set in the mind..Thank you

sir please tell us how to find Factorial Of A Large Number using modular arithmetic approach

This code works only till n

I have a small doubt When "num" has only one digit after 1st inner while loop why can't we use "if" instead of "while" ? Although I have debugged and saw the difference in the output But not able to figure out why is it while instead of if

Why did we store 2 in arr[2]? I didn't get that.

excellent teaching

bhai baht acha explaination tha ,just keep it up

thanks a lot brij ... you hero ...godamn saviour

At least I got the algorithm here. Love from IIT Kharagpur

Very well explained ...Thanks!!!

if we also want to find the modulus os the factorial

Nice Explanation,i love it

def fact(n); f=1 If n==0; return 1 for i in range(1,n+1); f=f*I return f n=int(input("enter no:"); factorial=fact(n) print(factorial) It's right or not ? Python program check it

I want to ask in your loop while num!=0 what is the problem in having arr[x]=num%10

bhai thoda shi se smja na

bro how to update includepath in vs code when working with boost library or headerfile

Love from Bangladesh bro... god bless ... ❤

You rock!.....cool approach

Really amazing explanation man, highly appreciated!

C++ library

The 0th index gives a lot of trouble😂

That was neat!

brother i implemented your array approach but it is showing runtime error obviously its in n2+n2.any efficient approach ?

Nice bro

thanks for this wonderful video

Could explain a bit more elaborately and slowly..it is kinda rushed

quite complecation too much varaible please optimize it

Thank You Bhaiya !!

Please help with the chief hopper problem (greedy algorithm)

Nice explaination sirji....

while(len>=0)

How would you do it, if you could only store numbers from 0 to 9 on each []. Because I honestly don't know how to put them together to make the limits of the loops.

well explained,thanks :)

can you explain its time complexity?

I need a flowchart and description of this factorial of large numbers program...

brother can u please explain how to create all magic squares of a 3X3 matrix this question is from hackerrank name magic square

Best explanation bro how can I think this way?

your okaay.....that tone is damn amazing haha

put x++ in while(n!=0) loop

Dude in the final while loop where we are taking care of the carry i.e *while(num != 0)* , why are we using modulo 10 on the *num* ?

great job

Can you explain in hindi ?

bhai agar factorial ka modulus bhi nikalana hoto

Thanks

Osum man!!

Can you Share your IMP notes files with me?

Can we calculate 1438 factorial using this process

great

nicely explanntion

bhai khudko padara hai ki sbko itti tex tex bole jara

That tension face for increasing size of video file :)

Use phython and live cool😎😎

super !!!!!!!!!!!!!!

bro please upload some videos and trick ....

Bro video is quite confusing. Its better if you first explain algorithm and then your code.

by this way we will get the tome complexity as O(n^2). plese optimize the code or else gavi us any new idea

num/10=0 how?

Make videos in hindi

Oookk😂

You literally fail to explain bro

Loved Your Explanation....Thanks!!!
