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.

my prgrm is taking only last pair of m and n to execute the function t no. of times... tell me some way to work it out

@Nikhil Bhandari: n^2 is the obvious problem.

@Adam Dzedzej:
Please verify Solution ID 8535255.
Getting WA even though all boundary cases are satisfied.
Please check.

I am getting time limit exceeded for n^2 what is the problem in my code

roshin i had a same problem (another program) and the problrm was that i wrote in c++ (g++ 4.0.0-8) but submitted it as c++(g++ 4.3.2) be careful maybe you have a same problem as me

what's the meaning of exceeding time limit? i know my program works but why does it says that? can anyone tell me?
