This article mainly shows you java how to find helix primes, the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor to take you to study and learn "java how to find helix primes" this article.

By spiraling the natural numbers counterclockwise from 1, we can construct a spiral array with a side length of 7.

37 36 35 34 33 32 31

38 17 16 15 14 13 30

39 18 5 4 3 12 29

40 19 6 1 2 11 28

41 20 7 8 9 10 27

42 21 22 23 24 25 26

43 44 45 46 47 48 49

It can be found that all the odd squares are on the lower right diagonal of the spiral policy, and more interestingly, there are a total of 8 primes on all diagonals, with a proportion of 8 ≈ 13 62%.

By adding a complete layer to the outside of the square, a spiral matrix with a side length of 9 can be constructed. If this process is repeated over and over again, what is the side length of the spiral array when the ratio of primes on the diagonal is less than 10% for the first time?

What can Java be used for? Java is mainly used in: 1. Web development; 2. Android development; 3. Client development; 4. Web page development; 5. Enterprise application development; 6. Java big data development; 7. Game development and so on.
