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

My solution in Python gets a TLE, but the same solution in java runs in 2.3s. You don't need Sieve to get your Java solution AC. And I just tested it with PYPY and I got AC in 1.01s. So I think it is the CPython 3 the one getting TLE. Last edit: 2015-10-07 15:36:29 |

0.43 secs after lots of tries. Very happy I made it. Python 3.4. Erathostenes and a little bit shifting did the trick Last edit: 2015-09-11 04:10:23 |

Sieve of Erastothenes isn't the fastest way to do this... Just saying. |

I wrote BPSW primality test:) But anyway how some guys have 0.00s on maxtest ? I have 210ms. |
