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 |

[code removed] its showing time limit exceeded.what to do ?plplzzzzzhelp!! (Mitch) --- "1. Don't post any source code here." You may try the forum for help with such things. Edit: I see that you already did, but you either didn't read TripleM's post "Read this before posting!" or you didn't take it to heart. So you might want to go and do that. But anyway your problem is simple enough, I'll reply to that thread you started. --- Last edit: 2013-12-22 09:32:30 |

@Rohan: I deleted your latest comment for obvious reasons. conio.h is not part of standard C, so there's nothing unusual at all about that error message. http://en.wikipedia.org/wiki/Conio.h |

Getting a SIGSEGV error in this <snip>.. Is this because of the large array? Last edit: 2022-06-19 12:32:06 |
