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

I've applied sieve, duration of the program with m=1 n=100001 10 times lasts for 0.56 s for me and I still get time limit exceeded. Any hint? (Python)

segmented sieve is more interesting than the normal sieve |

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

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: 2020-06-24 21:38:06 |
