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

I have attempted it using Python, but with a pretty naive approach.

I am using segmented sieve with range using c++ stl but getting SIGABRT runtime error can anyone help.The code runs fine on ide.

Hint: You can see that prime numbers always satisfy the 6n+1 and 6n1 conditions. So you can check a prime number by check if it is divisible by a number which satisfy 6n+1 or 6n1 ( of course, first you should check if it is less than 6).

Anyone can do this with Sieve of Eratosthenes ? To me it works but gets time limit.I use C++ Last edit: 20180429 03:29:44

What does runtime error NZEC mean?
