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

What the hell? I guess the maximum limit of m,n is 10^10 instead of 10^9. My codes work only if I assume the maximum limit to be 10^10 !! |

Is n really <= 1000000000 in test cases?

I have tested my solution on Pentium MMX 200MHz (much slower than this machine) and computing time was < 0.1s. Why do I always recieve timeout from SPOJ? |

I am totally new to SPOJ, can any once help me with the code submission i am getting compilation error because of file name and public class name mismatch in JAVA after submission. Even if i try to upload the *.java file with the same naming as the public class name. |
