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.

What does for every test case means

is there any chance to see where and what "wrong answer" appears?

Did not use segmented sieve ;)

I'm implementing sieve in Python 2.7. However, I get TLE, which I believe is due to the fact that I create a second list from 2 to the first number and then delete find multiples of the numbers in the new list and delete the occurrences of those multiples in the actual list. Is there a faster way for me to do this?
