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 a error of Standard input is empty what I need to do?

segmented sieve is more interesting than the normal sieve

I got the algorithm but I am getting Run Time Error in Python 3.7.

it took only 30 sec with very simple approach

Please can anyone can provide me with the solution in c++, as my code always gets TLE(time limit exceeded) error.

With the easiest possible solution for this problem, you can get it passed using C or CPP with slower time complexity, 1  3 sec. But I've done it using an algorithm(I'll not tell you, go Google it) and the runtime was 0.01 sec. The most efficient solutions are even less than 0.01s they are effectively less than 0.00s. So don't use simple logic. Go and do some research. Last edit: 20200624 21:38:06

Python3 TLE Prime Logic (TLE) convert it to C++ and it will get accepted like a charm.! Shows just how important C++ in CP.!

After I submitted my problem it says "time limit exceeded". Then I clicked on "ideone it". And after running in ideone I saw that it's taking less than 0s to run. Still my answer not getting accepted.

it says wrong answer but where to look which is the wrong one in python 3.7

All the time getting time limit exceeded with python. Even with segmented sieve smh
