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 just spent 30 minutes working on this, and then added on an if statement to remove the '1' I always get, and then I got it right. Spent 30 MINUTES working on optimisations, and it was all because of a ONE |

What should be the output if there is not prime number possible between the the range for example : 25 27 ?? |

test cases are weak solved it without using sieve |

<snip> I ran it on vs code. Its absolutely fine there. Can anyone say why its showing wrong? [NG]: Don't post any code here. Use forum for debug help and discussion. Last edit: 2021-01-12 22:48:29 |

brute force works but segmented sieve gives tle |

Sieve will give a runtime error because the array size(n>10^9) is too large to be stored in ram use segmented sieve |

I thought this is a easy problem but....when i saw sieve algo....then i am start crying |

Test cases are definitely weak. I got away with ~7s processing for some cases. |
