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.

To everyone who getting TLE, use segmented sieve

You can solve it , it is easy enough.

what to do in case of m = n = 1

vats_ayush: 2022-09-21 17:17:37

how to handle the case of m = n

i am unable to solve it.

use segmented seive.

I am getting runtime Error

rest_less: 2022-07-18 08:02:20

i have used sieve but gettign wrong answer

I think I solved it in an optimal way using sieve method I don't know why I get TLE !

Who is getting the Time limit exceeded issue try this solution?
Don't forget to follow on github.
