TDPRIMES - Printing some primes |
The problem statement is really simple. You are to write all primes less than 10^8
Input
There is no input.
Output
To make the problem less output related write out only the 1st, 101st, 201st, ... 1st mod 100.
Example
Input: Output: 2 547 1229 ... 99995257 99996931 99998953

sieve of eratosthenes gives AC in 0.93s (with printf) Last edit: 2015-02-17 14:18:38 |

@ALL people who solved it in under 4 seconds. How?! A hint at least! My implementation of sieve (using only 1 or 5 mod 6 numbers) as a bool array takes 9.xx seconds and bitwise sieve of integers takes 7.xx seconds. How to optimize further? Update: 6.62 s after using Atkin. :/ Last edit: 2014-12-09 20:08:13 |

We can easily bring this under 1 sec, just lil coding needed.i wish the timelimit was under 2 seconds. Would have been much more fun.lazy i m . |

@surayans tiwari IDEONE is using **CUBE** cluster and here SPOJ is using Pyramid cluster...CUBE id 20X faster than Pyramid. http://www.spoj.com/clusters |
