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

using seive will cause lot of memory for very large numbers . Just read the question we have to only output the prime numbers simply go by traditional sqrt(n) method or use segmented seive.

would anyone please tell me what sieve is? i'm new for SPOJ

finally got the solution in python

finally got AC!! after 23 TLE.same logic of python works in c++ and in python its tle .

I tried Sieve of Eratosthenes>TLE

Description says "between", however the second sample test case contradicts this.

time limit exceeded.. means?

The classical O(n2) solution gets accepted but segmented sieve shows TLE.. How is it even possible?

why isn't sieve working??
