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

READ THE FULL STATEMENT AND USE OPTIMISE ALGO SIEVE TO FIND PRIMENUMBER , YOU CAN ALSO USE BLOCK SIEVE TO OPTIMISE MEMORY |

Can Anyone please share the solution in Python. I have tried everything from normal sieve to bitwise sieve ,however bitwise sieve will only reduce the array size from 10^8 to (10^8)/64. What about Time complexity even if you are skipping even numbers then the time complexity will be around (10^8)/2 i.e 5*10^7. I think under the given time constraint, the no. of iteration possible is only 10^6. I also have used Fast I/P O/P method but still nothing happened. Please Help!! [NG]: This is a site where we code solutions, not share them. Submit as PyPy, although trying to get a better time with PRIME1 first will get you further in long term.

Simple Sieve will do the job , no optimization required . Last edit: 2021-08-02 21:40:33 |

Just use simple sieve , declare a global array of size 10^8 and it goes AC !! |

used vector instead of array, replace cout with printf and endl with \n, TLE will be removed. |
