There are lot of prime problem's in this site. But my questain is only prime generation. Because most of the good programmer's are use other technick to solve this type of problem's. I want to know what is the minimum time to generate prime in 20000000(only marked this are the prime) ?
U can mesure ur time by using uva submit script. I have known my prime generation time by this way. I have submit only my prime generation code
and my problem was 10394. To mesure my time i have used only prime
generation code not the problem's solution.
I want to know who take the minimum time to generate prime in 20000000.

what ever ur time ? please mention it if u have enough time.
