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, nm<=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 5Warning: 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.hide comments

no need of using sieve here

sieve divided in segments

AC finally! use segmented sieve Last edit: 20180123 16:19:22

run from 2 upto square root of number while checking for prime Last edit: 20180121 13:27:10

@hsakiv220290, a prime has exactly two divisors, the number 1 only has 1 (itself)

use segmented sieve, normal sieve will give TLE

for TLE no need of Sieve algo., filter the numbers against 2 to the square root of the number. Accepted.
