Thread: math problem using recursion?
Post: RE: math problem using recursion?
| As for the previous questions, the only requirement for the start number is that
it is a semi-prime. And I doubt whether the chain lengths would ever get above

Thread: math problem using recursion?
Post: math problem using recursion?
| First the problem.
1. Start with a semi-prime (eg, 15 = 3 * 5).
2. Take the factors and concatenate them both forwards and backwards to give 2 new numbers. (Ie, 35 and 53)
3. Test for semi-prime-ness.... |
