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 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

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: 2020-06-24 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

Is it not possible to answer this question using C? My code keeps exceeding the time limit |

I am getting runtime error. I am using brute force in python. I also tried using the sieve of eratosthene but I am still getting runtime error. Is there any more efficient algorithm for python users?

I'm getting time exceeded warning when compiled on C . Any one help me!!!

I'm not getting the question clearly.

If you try your Python3 (time limit exceeded) code in C++, you won't get that error. |
