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.

using sieve and still nzec

using devc++ ide on which compilation time is coming around 1.40s then also on submission showing TIME LIMIT EXCEEDED error

I've tried it many times, made my code more efficient, yet the time limit is exceeded!

vaibhavahuja: 2016-06-16 03:20:23

yeah, time limit exceeded. come on?

mychemromance: 2016-06-13 16:17:58

Time limit exceeds all the time!

time limit exceeded??

Only 2 submissions not TLE in nim. hahahaha.

Are we to hardcode a list of primes in the nim source code?

cdgid7: 2016-06-07 11:00:10

C++ used about 2s and accepted, but lua got TLE with same algorithm

My algorithm is working fine on ideaone as well as locally even with large values. But I keep getting Runtime Error NZEC. Has anyone else seen this issue?

time limit exceeded. java is slow language, so PROBLEM SETTERS should give more time limit if the answer is in java.

There's 1000 java users under 0.36s, time limit is 6s. You need to improve your method.
