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.

@Riya ..the input/output are from/to the standard input/output file...given the large values...use long int, should work if you are confident about the algo

Riya Midha: 2014-05-28 15:34:34

in what form should we take input and give output??

Riya Midha: 2014-05-28 15:33:50

my code is working correctly and giving proper solutions but here it is saying wrong answer ....is it because of the input and output method????

Guess there is some issue with the Java Compiler. Code runs fine in eclipse. but it shows compilation error here.

The first line is a single number, indicating the number of lines of input that follow.

How does one know that the user has finished entering input values? Say he gives just 1 line of input--> 1 3. (Nothing afterwards)How is this handled?
