PRIME1 - Prime Generator
Peter wants to generate some prime numbers for his cryptosystem. Help him! Your task is to generate all prime numbers between two given numbers!
Input
The input begins with the number t of test cases in a single line (t<=10). In each of the next t lines there are two numbers m and n (1 <= m <= n <= 1000000000, n-m<=100000) separated by a space.
Output
For every test case print all prime numbers p such that m <= p <= n, one number per line, test cases separated by an empty line.
Example
Input: 2 1 10 3 5 Output: 2 3 5 7 3 5Warning: large Input/Output data, be careful with certain languages (though most should be OK if the algorithm is well designed)
Information
After cluster change, please consider PRINT as a more challenging problem.hide comments

when i compiled this program on my pc the execution time was 5secs which is less than time limit for this problem...but spoj produces the error "time limit exceeded " can anyone help?

@Neha: as suggested, it's a segmented sieve, not a full sieve.

@Giovanni Botta I tried using Erathostenes sieve but the heap runs out of memory.. |

@ Giovanni Botta : I tried using Erathostenes sieve but the memory of heap is not to save such large numbers. How did you do it? |

It would be fun using Template Haskell so the calculations are done at compile time :D |

Still getting WA. I have NO idea what's wrong with my code: I tested multiple cases and double checked the results with Matlab. No apparent mistake! |
