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

if we are using sieve how can it be done without taking an array of size 1000000000,

@keshav as far as i know if you allocate an array of size int(1000000) if gives runtime error in many compiler maybe thats y u r getting.

Hi when i run my program on local computer it works and generates the right results and when i test it on Ideone.com it gets the green light and generates the correct results.
