For convenience, prime numbers under 10^5 can be initialized. Edited by author 03.12.2012 03:00 Edited by author 03.12.2012 03:00 Re: Hint..

IMO this is wrong. 85 = 2 + 83 is the counter-case. > For convenience, prime numbers under 10^5 can be initialized. this way too big. :) Edited by author 12.01.2019 19:53 Edited by author 12.01.2019 19:54 |
