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 |

What should be the output in case m = n (and assume m is not prime)? Should be it only black line or nothing at all? |

Runs in 0.12 sec but gives Wrong answer. I run as many test cases all over the range of values indicated and it works perfectly. Are trailing \n ignored (on end of output)? |

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 |
