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 if the input : 1 1 1 the problem does not specify the lower bound of n-m... so n-m=0 is legal ? Last edit: 2014-01-19 10:47:51 |

@Babita u're scanning only 10 first digits, no matter how many cases is bound to be done. Besides writing anything BUT the answer mentioned in the description will be tolerated as invalid. |

I am getting wrong answer as the reply, But I am getting the right answer for the test cases. I added a new line between inputs aswell. I am not taking the inputs with a space in between, is that necessary? <snip> Last edit: 2022-06-19 12:33:55 |
