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.

T*(n-m)*log(n) using miller-rabin gets TLE ?? lol weird

Don't use seive algo just simply use sqrt(n) complexity prime check on each number.

TLE!!HOW TO OVERCOME IT????????

I literally worked on my sieve, but for 10^9 it could only run in like 13 seconds, so not under 6 seconds :( I resorted to brute force style i * i < n

Since python is a slow language, shouldn't you choose a faster one?

Since python is a slow language, shouldn't it get more time for execution?

Having TLE in python should i switch the language

wasted lot of time using sieve sqrt(n) solution works.

TLE....WHAT TO DO?

works in terminal. i think my problem is with the io. can figure out why they format it this way.(python)
