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

for those who complain about code work very fast in ideone but get tle in spoj should try to input the maximum number of case that contain maximum number of n-m. |

@Risto: SPOJ servers are slow. Optimize your approach. |

The execution time of my program is 0s, which can be seen here : http://ideone.com/NfrMUA but it says time exceeded on SPOJ. Any idea why? |

To those of you getting TLE. Think about what the hardest possible test case is. |

do we have to give a condition for the boundary conditions in our code ? (i.e for the number's range) Last edit: 2013-11-01 11:50:28 |
