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
5
Warning: 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.

I'm using Sieve of Eratosthenes algorithm but I keep getting TLE! no matter what algorithm I use. http://ideone.com/2Om20c

Why is my code showing wrong answer? It's working quite well in ideone. There are no test cases. We can't see the output. Nor can we see the optimized solution. Can anybody help, please?

I have issues compiling the code in SPOJ. It works in eclipse though.
I posted a question in stackoverflow. Could someone help me solve this. Thanks.

Same logic doesn't work in C and runtime error is shown... Don't use scanf and printf...

cout and cin is working.... Enjoy!!

My code works in my ide and also ideone.com but here it says Time limit has exceeded.

My code works. I use the ide compiler and it works. Yet when I submit it, it says that the time limit has exceeded itself.
