For this question do we have to break it into 3's and take the last remainder if any and then product it.
A Geek has a rope of length L meters. He wants to cut the rope in different parts of integer lengths. The Geek wants to make cuts in a way that maximizes product of lengths of all parts. For example, if the Geek has a rope of length 10, the maximum product he can get is 36 by dividing the rope in three parts of lengths 3,3 and 4 How does he make cuts for a given rope of length L
Aayush, we will soon post the solution.
Possibly the best resource I could find. Could be altered for integral solutions.

Thanks geeksforgeeks for such a great work. It has helped me (and a lot many others) to prepare well for their dream jobs and achieve it also. When I came across this site I quickly realized that this site is going to help me in big way and so was done.
Once again thanks and I hope it will continue addition of new questions and go way ahead guiding not only professionals but also a bigger success platform for its owners.
Hi Geeksforgeeks team,
One suggestion from my side is that the way questions are presented in the interview corner.When I open the link for a particular company , I get all the posts done by people on the forum for that company.But the problem is that , we only get the main heading of the question.We have to open the link ,after that only we get the exact question.I would suggest that ,we could be able to see the question from the main page itself ,instead of opening the link.It was like this, before the site up gradation took place.It will make browsing the questions easier.
good work....& thank you
Awesome work by Geeksforgeeks
hats off to the team
Thank you
Thanks for the whole repository of questions and organized portal for interview question.
I have a criticism though, regarding the articles I see here.
GFG does an extremely poor job in providing the intuition as to how they arrived at the solution.
One bad effect of not having the logical path to the solution is that the website users will tend to memorise the solutions, which will cause more harm than benefit in the long run, besides forgetting the solution itself shortly.
Memorizing solutions is not at all recommended. GFG is not just an interview discussions forum. There are many articles beyond interview purpose. Our main focus is to present various problem solving strategies.
We would encourage the reader to try solution on their own, only then look at the solution. If anyone glances at solution he or she making damage to their skills improvement. If they find better solution, we would like to present the same on GFG to help other readers.
Hi Geeksforgeeks team,
I wanted to know how do I get the company specific questions.Recently after the site's 'interview corner' maintenance I am unable to browse company specific questions.Suppose I want to see all the questions posted by people on adobe interview , how do i access that like I used to before.
Please help..
@vikas: We are working on this and many other new features for interview corner. We will be updating you once these features are available. The interview corner is not in maintenance mode, it is available now.
Is there a way to get a mail for each post/comment on geeksforgeeks to my personal gmail.
carrercup has an option for this, so it allows us to be up-to-date all the time and we will never loose track of the details.
I understand that this feature is there for AboutUs, but it would be great if this is there as a general setting for an account.
How can I register?
You do not need to register to comment on blog. For forum, you can use use the link given on top left of forum.
I'm not able to post my comments/doubts anywhere!
The bar just scrolls up to the top of the page as soon as I hit submit. Whenever I repost the same comment it detects duplication...Yet I'm unable to see my comment anywhere! Are you guys moderating the comments?!
@algobard: We have enabled comment moderation. We were getting many unrelated comments.
Thanks for the effort!
However, I would suggest you start implementing code for algorithm articles in Python instead of C++. Implementing code in C++ makes it much more elaborate and puts the focus on language rather than the algorithm itself.
On the other hand, when you implement it in Python, it looks exactly like the pseudo code and makes it much more readable.
Good Job Guys!
Keep the good work going.
Hello sir,
Please update all G-facts on the G-facts section.
i will be greatly thankful to you.
i think you removed rest G-facts from the G-facts sectio.
@Amit: We have moved most of the G-Facts to C/C++ puzzles category. The reason was to have a better readable titles. G-Facts are still there with different titles and categories.
Thank you sir
There seems to be no good way to fetch all titles related to a specific company (search returns everything containing that keyword). It'll be great if you could add some sort of "tags" feature, clicking on which will return results that we can then sort, based on time etc.
Thank you so much... for wonderful work...
It helped me lot in understanding algorithms and data structures
Very nice site. I gone through different sites for gate questions with solutions. But none of them upto the mark. Some are asking for login. Really so thankful to all for your contributions. Expecting more gate related topics for cse.
Thanks for your comment. We are working to improve it further.
Keep visiting the site.
Thanks you.
Hello GTG team,
i had few non-technical doubts...n wanted to clear with your team...
i am about to join wipro for SAP but still for next one year i want to try for amazon,yahoo,ms.
so i wanted to ask that:
Ques> Companies like Amazon say fresher 0-2 can apply, so does it matter that whether the candidate is from SAP{or any other field that is not in Amazon} or is idle unemployed,
if candidate is in range 0-2 can simple apply and get the job?
Ques> once rejected by Amazon so after how much time we can apply again in it?
Ohh... not reading GFG past few months, there are significant posts from readers. I am happy that our leisure time efforts helping many students and professionals. Great work, I appreciate creators of GFG for their idea.
Contentment on learning side and due to comments from readers.
These days not finding time to contribute.
, hope others are filling the lacuna.

/* Very useful .....thanks.. */very useful
Thanks
hello members i want to ask about Karthik ? Hey man are you Karthik Raghavan from IIT MS 2008 batch ??
from IIT madras and senior/friend of Prasanna Karthik?
After many not-so-reliable interview questions forums and reference books in pseudo-code, this site perfectly fitted my bill.
For bridging the gap between theory and practical implementation. Thank you !!
P.S: I love the syntax highlighting.
After many not-so-reliable interview questions forums and reference books in pseudo-code, this site fitted my bill.
I am surprised how perfectly you bridge the gap between theory and practical implementation. Thank you !!
Thanks for the comment. keep visiting the site.
I would like to appreciate your work. Really quality stuff. I learnt a lot from past 1 month.
I am not able to find good book on data structures and algorithms. can you suggest one book.
Thanks,
Venkatesh
Definite a great website, hope it can help me beat Amazon...
Thanks to this site.. I cud crack Microsoft
Thanks for your comment. Keep visiting the site and contribute further.
Good work guys. Appreaciate the effort.
Please send me the email address of your web administrator.
@Brett Fank: Please contact feedback@geeksforgeeks.org
good work guys.
Plz post tutotrials of Trie,Suffix trees and String Matching algorithms like knuth Morris and Boyer-moore with running C Code and algo.
really thats much needed along with the applications of suffix tree and tries please post how to make such trees
@nikhil jain/Ajeet:
You can find a detail article about TRIE with implementations for all operations along with good coverage of application.

Hope you guys find it useful.
Hey guys it's been a long wait for the design patterns section
....waiting for it.
Also segregating questions on OS would be really good! Keep up the good work...
Hi, this website is really awesome.
I would suggest you to add all the data on this website in a pdf file. That would make easy for programmers to learn as they would get whole material at one place.
why do not u add some thing like "c/c++ program evaluation tool" to the site?
Possibly the best site I've ever come across..Good show!
Its really a vgreat website..i hae found most of the important questions in this site.U could also include the facility for receiving questions on the mail on daily basis(10 to 20) depending on the request of the user,like data structure ,c ,os ,c ++. It would really be nice if u include this feature.
Thanks
Nice one ...
Some of my suggestions ,
1. Tagging questions bases on company is very imp as people seek the types of questions each company ask .
2. To attract users who are exp , trying adding feedback to company profile , the kind of work they do etc
3. As you have started differnt page for topics like Arrays, Bitmagic , some notes from good books and other sites will help.
Hey guys, didn't know about this until i saw the mail from Gautham. you guys will rockm, and go great lengths. all the best for your future, and i look forward to pointing this website to wannabe geeks for sure!
super. thank u very much
nice work
Guys, good work, keep it up. Can we have one more sub-title for "Design Patterns"? May be it is bit advanced for beginners, yet many professionals are browsing the site.
Thank you, Venki.
Having Design Patterns is definitely a very good idea
But we want to go in phases. After covering object oriented progrwmming, will be covering design patterns. Thanks for the suggestion.
Good idea, step wise. Let us start discussion on Object Oriented Principles preferably SOLID and GRASP.
http://en.wikipedia.org/wiki/Solid_(object-oriented_design)
http://en.wikipedia.org/wiki/GRASP_(object-oriented_design)
Guys the book "Head First Design Patterns" is just awesome.. try reading it in conjunction with http://sourceforge.net/projects/hfdp-cpp/ if you are addicted to C++.
Good work. But how about including solution in java too...please let me know where we can contribute solution in java...
Asit, posting solutions in java is a good thought. If you have solutions in Java, you can add them in comments of the individual posts.
We are considering adding Java solutions to the main posts, but is not in our priority list due to the effort involved.
Hi Sandeep,
Very good work....keep continue this good work...
@Deepak: You can add your query to forum by using "Ask a question".
For a C++ query, select forum category as "C/C++ Programming Questions"
Hey tell me sandeep how do I post queries of C++
@sachin: Sachin, GeeksforGeeks was born out of the experience of three technology passionate guys with different backgrounds.
Sandeep used to work in a big MNC before he left to pursue his passion in teaching. Gautham, who graduated in Electrical and Electronics Engineering, now works as a software developer in a famous MNC.
