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, nm<=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

Hint: do not use sieve(or segmented) O( (n  m)* p) = 10^4 * 10^3 < opns possible by 3 GHz processor Last edit: 20170117 18:48:06

don't use the exact segmented sieve, read the segmented sieve and use your brain a bit, and you will get ac ,one more advise take long long ,chances of overflow

The program works as intended on my device. But I get 'time limit exceeded' when I submit my solution. I am not sure what that means, or what I can do to change that.

i am using segmented sieve method and still getting time limit exceeding error

Hint:Use segmented sieve for this

Time limit exceeded, what am I supposed to do now ?
