I am fully agree with Rasel. Hope some step will be taken by the administrator so that we could easilly find the book reference.

Thank you for your kind info. It is very much help full. :D I am feeling better in coding JAVA when submitting solution of the ACM problems. But it is noticible matter that there are too few solver who are solving problem in JAVA though it is more easier to solve some particular complex or some kind...

How one can submit problem to the problem set archive? Is there any particular rule for submiting problems?[/url][/cpp]

Yes Suman you are right in all respect but we are now a long way from solving the big int relating problems. [/img]

I have the same voice with you. In Real time contests, classes are not so usefull and make difficulties when implementing them. And odd situation??? Yes we are always in odd situation in real time contest..

I can't understand why time limit exceed.... Can anybody help about the problem???? :cry: :( :cry: :( #include<stdio.h> #include<math.h> #include<iostream.h> long primes[10000]; long pc; long p1,p2; int isprime(long num) { ??????????????? } void genprime(long lim) { ??????????????????? } int main() ...

Contact me by my email address. I can help with that problem....Rajib Mazumder

:-? Isn't class variables and functions share more memory than simple string processing with pointers? :roll: I think for contests (real time + online) if string processing used with pointers that will be more fast and take less memory. But dangling pointers can crash the program or make RTE ! :win...
