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.

if (time limit exceeded) your program is running not enough fast. test your program with max possible values
if (runtime error) your program has unhandled exceptions

i am finding runntime error how can i find it

reduce checking if you got TLE. you don't have to check for all divider. think about it. minimalize it

i also have a problem with "time limit exceed". i dont know what wrong

My solution got wrong answer although my output is correct!
I did limited 1 <= m <= n <= 1000000000, n-m<=100000; t<=10; m <= p <= n
Did I miss something ?

time limit exceed and don't know what to now.I solved it but...

use segmented sieve for best results and modify sieve according to requirements
