SPOJ.com - Problem PRIME1

PRIME1 - Prime Generator

#number-theory

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.

	amitray: 2015-09-04 09:31:39 My code works perfectly in code::blocks. I first enter a number if its less than 1 or more than 10 you need to re enter the number. Next the loop starts with first number as input. He enters two numbers separated by a space each line. Than preses enter. the output is produced as it should be. Still i get wrong answer. What is the reason? Correction: I was wrong. It was not printing the last number if it is prime. I have solved it. Answer has been accepted. Last edit: 2015-09-04 09:40:59
	eapostol: 2015-08-31 05:55:09 can't get it to work on ideaone either, getting timeout error here but works fine locally.
	adityavasistha: 2015-08-30 17:35:29 showing time out
	revolt33: 2015-08-30 11:27:16 finally did it, took me 3 days to solve... :P
	apprentiz: 2015-08-28 07:52:59 working fine with codeblocks within time limit. here it is showing timeout.
	magma1983: 2015-08-26 19:57:55 Sample correct in ideone, Python. In SPOJ: -Time exceeded in Python 2.7.10 -Wrong answer in Python 3.4
	satylogin: 2015-08-25 08:50:51 the same problem is happening with me
	aloysiusabreo: 2015-08-24 13:19:38 working fine on ideone and codechef ide. shows runtime error on submission. any ideas?
	vtaneja: 2015-08-24 10:29:07 I am getting timeout... For input: 1 999900000 1000000000 My functionality including printing timing is: 1515 ms. I am trying to find out input set of the problem. Does anyone have any knowledge of the input set?
	Tanvi: 2015-08-23 14:05:28 getting SIGSEGV error. My code is working fine on Ideone. What should I do?
