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

segmented seive means applying simple seive again on already computed primes(small range) to get primes ahead

anyone got AC in python 3? i am using segment sieve... still TLE

ARH.... my (C++) code works perfectly fine, but i get 'wrong answer' all the time.... this sucks if you don't get any advice why it's wrong if it works..... :/

I've used 2 to sqrt(number) to solve the problem.Solution is accepted but the time is over 1 sec(1.15). How do I reduce the compilation time. BTW I've used C++ to code.

no need of using sieve here
