I'd like to know what are the best sites to learn about formal languages, automata, algorithms and data structures. Preferable with many solved questions...
Thanks in advance
What I prefer is., a best book " On Theory of Automation", http://www.amazon.com/Introduction-Automata-Languages-Computation-Edition/dp/0321455363 .,
I have read this book., superb it is.
visit http://rosettacode.org/wiki/Rosetta_Code
You can compare also structure of programs on examples.
You didn't mentioned what kind of algorithms you want to learn. Anyway for basic algorithms and data structures TopCoder algorithm tutorial's page is a good place to start. Visit http://www.topcoder.com/tc?d1=tutorials&d2=alg_index&module=Static

This question was asked in an interview. First, I came up with B-tree. He asked me to be more specific and asked me to describe how I would store the data so that it would be easier to retrieve.
Can you please throw some light on this. Thanks in advance
You question isn't really clear.
"Good" ways to store the data depend on what you want to do with it.
If you want access parts of your data, a list of offsets suffices. If you want to search in text, using an additional inverted index in combonation with docIds->offsets is great. If you have frequent updates to your data and reading is rare, none of those make sense. So it really depends
Sounds like an open question, so you can demonstrate your vast experience of ... well, http://en.wikipedia.org/wiki/NoSQL would be my guess, but you could argue that http://en.wikipedia.org/wiki/Dbm answers the question.

I wonder If there is a place provided many algorithms.
I want to know the details of some process´s schedule algorithms.
For example, If I want to get some informations about Network, I will check out the RFC documents. I want to know, in the field of os algorithms ,if there is something like RFC.
Further more, If there is a place I can read lots of algorithms in many fields. In my view, Reading the algorithms in many fields can help me a lot in algorithm ------Anyway, someday, maybe I can combine two algorithms to solve one particular problem.
Thanks.
How about this: List of Algorithms. Also you can study Donald Knuth's The Art of Computer Programming Vol 1 - 4.
Wikipedia has lots of them. I don't think that there is not any organization that provides algorithms for OS.
Wikipedia holds a lot of algorithms.
Use section "See Also" there.

Please suggest me some good materials or books or links that provede the methods to find the complexity of algorithms that use linked list for their implementation. My question may sound silly to some of you but please reply.Please help
Introduction to Algorithms is the canonical textbook.
It is possible to find a complete PDF of this book online. I'm not going to provide a link, though, because I'm not sure if these copies are legal.
If all you're after is a quick reference, then Wikipedia is the best place to start. For instance, see the table at http://en.wikipedia.org/wiki/Linked_list#Tradeoffs.
Gautam I have a feeling that you are trying to skip the understanding of 'complexity analysis' portion and jump to linked-list-complexity-analysis.
Just so you know, if you want to understand it truly, then you have to understand two parts
1. How to compute complexity of an algorithm
2. The flow of algorithm in question.
'linked-list-complexity-analysis ' is not something that you can understand without understanding {1}
That said, if at all you want ready answer (trust me that wouldnt help you in interviews), you can refer to this book "Data structures and algorithm and applications in C++" (http://www.mhhe.com/engcs/compsci/sahni/)
Highly recommended for beginner.
Immensely boring, and I doubt you will read it again. :P
You will find answers to your specific questions there.
After you are done with that book , I would suggest go with DataStructures using C/C++ by Langsam/tennenbaum.

The programming language or The programming logic.....
Because both are equally important for good coding practice. And, please justify your answer.
What makes a program to be a good program?
Being able to address the customer needs and make him happy.
Programming language, programming logic, code style etc. are nonessential to the success.
The programming language doesn't have squat to do with a good program, you can write ugly code in C++ and elegant code in LOLcode and if they perform the same function nobody will care. Most important is that the code is bug free and performs its function.

I need learn some algorithms. What is the best collection of algorithm exercises that is like Project Euler?
These are the ones that I know of, which are good and are used by many programmers.
