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.| Added by: | Adam Dzedzej |

@Ahmed.Mahmoued So there's a blank line only in between non-trivial cases and no blank line at the end? That's very confusing and not specified in the problem statement! |

@Giovanni Botta input 3 1 1 56 70 11 15 Output: 59 61 67 [blank line] 11 13 |

Getting WA over and over. I'm a little confused about how the output should be formatted. Is this correct? Input: 3 1 1 56 70 11 15 Output: [blank line] 59 61 67 [blank line] 11 13 [blank line] |

@ Michael T.: thanks! will look into that. Just out of curiosity, did anybody solve this using Erathostenes sieve? |

oh boy, this problem really frustrates me all day. even though the input and the output is correct. they take it as a wrong answer -______-. any idea guys?. oh, i use c for this problem, and i am a "noob", so i can't figure it out how to apply the sieve alg. Last edit: 2011-10-27 18:53:27 |

number greater than 10 it should not divisible by 2,3,5 and 7; n output for no. less than 10 should be checked separetly |

Yes indeed! It is a segmented sieve |
