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.hide comments

for tc m = 1 change it to 2 to avoid printing 1. |

you can save answers in unordered_map and find divisors in range of [2,sqrt(x)] |

is it possible to create an array with 1 billion items in C++. I met SIGTERM error |

my solution works totally fine using segmented sieve in my ide (g++ version 8 (something))

What might be the problem if I get runtime error? |

if you got TLE, may be you looped check prime from 1 to n, just change it to check from 1 to sqrt(n) then it should be OK |

what the f**k is that I used the sieve of eratostenes and TLE but when I don't, I passed
