PRIME1 - Prime Generator

no tags 

Peter wants to generate some prime numbers for his cryptosystem. Help him! Your task is to generate all prime numbers between two given numbers!


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.


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.


1 10
3 5


Warning: large Input/Output data, be careful with certain languages (though most should be OK if the algorithm is well designed)


After cluster change, please consider PRINT as a more challenging problem.

Time limit issues in Python.

@dr_strange - Yes, i did it using a simple property of prime numbers.

this is very hard in Scala... What about time limits BY language?

Finally done it.

dr_strange: 2015-05-17 20:45:40

is there a way to do it without sieve

I took an array of a[n] but it says a is too large . what should i do ?

This problem can be solved very easily without even using sieve :D
