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'm always getting "time limit exceeded". I'm using C++ with vector at the beginning, then after I'm just using pure arrays, but I'm always getting this! :( |

@Kumar Gaurav SIGXFSZ is a sign that you output more than 33MB of data... Check this link SPOJ Forum is a good place to solve this type of error Last edit: 2013-09-18 12:47:24 |

for each of the invalid inputs, do we exit the method or re-accept it using do-while loops? #java |

My code is working perfectly fine when I tested by providing the input file exactly in the format required. But I don't how would it work when I submit it. Please let me know, if I shall have the provision to provide the input through file or just keep it run-time. |
