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

wats the solution to get rid of time limit exceeding problem..??

MY programe works fine, time limit is 6s, in worst test case it works for 4.84 s on ideone.com , and it's always Time limit Exceeded :( Why??

how to solve sigsev error?

i m new here.. i think the problem can be done by using sieve erosthanes .. starting with 2, we check every prime ,and separate the composite ones, for each test case, we can check in btw.. i know it sounds obvious, but could you help me, in finding the soln..

@Julian Leyh: There are already 20 AC Ada solutions. You have to think about another approach ...

Heap for Ada seems to be too small.. I can't allocate an array of Boolean with 1000000000 elements.

you'll have to use sieves to generate primes maybe upto sqrt(10^9) and then running the sieve again on the nos. bw. m and n using those primes you have calc. earlier.
