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 |

I don´t know how to output test cases with no primes in the range. So, What should be the output for this input a,b or c? Another thing, the output could end with more than one new line after the last prime? Input 2 1 10 4 4 3 5 Output a 2 3 5 7 3 5 Output b 2 3 5 7 3 5 Output b 2 3 5 7 3 5 Last edit: 2013-08-30 04:50:36 |

My java code working fine but it's timed out. I might need to change the code to write into stringbuffer to print on console at one shot. But I welcome any suggestion. Thanks |

I believe I have some problems with input and output, as my solution passes all tests which I can only imagine on ideone... <snip> Last edit: 2022-06-19 12:30:40 |

haha I have realized, to solve this quickly, you have to avoid O(n^2) Just make sure you avoid same calculations twice :-D |

yhm... I implemented solution in Ruby and it passes all test cases which I created however it shows Wrong Answer when I submit it to SPOJ. here is code and some tests on ideone: <snip> If someone could suggest what could be wrong. Last edit: 2022-06-19 12:32:37 |
