Re:请问这句怎么理解,卡在这里了，"You are also to compute the number of values 0 < p <= N such that p is not part of any triple (not just relatively prime triples)." 谢谢In Reply To:请问这句怎么理解,卡在这里了，"You are also to compute the number of values 0 < p <= N such that p is not part of any triple (not just relatively prime triples)." 谢谢 Posted by:youngtrips at 2007-08-26 12:02:02 让你辛苦等了两年半，我来解答你的问题吧。
对于方程x^2 + y^2 = z^2有解(triples)为(x,y,z)，
p = |{k|k!=x && k!=y && k!=z for any(x,y,z) that fits x^2 + y^2 = z^2, k <= N, k为正整数}|
