请问
return Triangular_iterator( _beg_pos ); 这句话的语法是怎么样的？
Triangular_iterator是自定义的一个class吧，class后面直接加（_beg_pos)什么意思
呢？
如果是返回一个Triangular_iterator的object, 不需要定义成
Triangular_iterator obj(_beg_pos）；
return obj；吗？

发帖数: 33 | 5 The division into triangulars is not a problem. Assume 顶点s are labled
as A1, A2, ..., An. Then can always choose A1A2A3, A1A3A4, ..., A1A(n-1)An.
When calculating the area of each triangular, remember it can be either
positive or negative (based on the particular ordering of the three
end points AiAjAk), which means each triangular can either have a positive
mass or a negative mass. This will take care of 凹多边形.
Of course, if catalina's formula is correct, then that is easier. :) |

既然老二和老大不同，我觉得你不应该过分拘泥于老大的教训而刻意避免早教。
我讲一些我儿子的例子。我儿子喜欢数字序列，三岁多的时候，坐在车上，他总是要求
和我讲数列，譬如2，4，8，16，32，...他要一直讲到上万，直到我大笑投降为止。
有时候，在饭桌上，我给他讲奇数偶数，问他奇数加上偶数会怎样，他兴致盎然，继续
去琢磨奇乘偶，偶除偶的结果。还有一次长途旅行，在车上和他讲起质数的概念。后来
有一天他在学校没事做，便找了一张纸尝试列举前150个质数。我借过关于罗马数和二
进制的书，有好多天，他的乐趣是缠着我，互相出题，比如382的罗马数是什么？48
的二进制怎么表示？又有一次看到triangular和square numbers的概念，在店里买菜，
他忽然问我：在1之后，哪个最小的数是both triangular and square number？这是
他自己出的题，我一时都没想到答案。
我儿子现在五岁两个月，教授这些知识，当然算是早教了。他学得很轻松，又喜欢，他
觉得数学很有趣很神奇。在这些知识的基础上， |

produce a sum that is a square number, what is the largest possible value of
x or y?
Triangular numbers less than 100: 1,3, 6, 10,15,21,28,36,45,55,66,78,91
A squre number less than 200: 1, 4, 9, 16,25,36,49,64,81,100,121,144,169,196
Apparently 45 + 55 =100. So we know at least 55 is one possible choice.
Can we go any higher? Let's try 91. 196 is out. 169-91 = 78
Bingo.
The answer is 91. |

来源The Scandinavian-Welfare Myth Revisited
译者ifei
奥巴马如今看起来甘愿在增加美国福利方面付出任何代价，而谈论到福利国家，我们无
法避免会把北欧国家作为既提供大量福利又能保持经济繁荣的完美例子。这看起来确实
是一个谜团，特别是对于包括奥地利学派在内的自由主义者来说。北欧的经济就像大黄

，我经常要被问到如何解释这一现象。
要考察一个国家的经济表现，看看这个国家的历史是一个好办法。斯蒂芬·卡尔森于
2006年写了一篇优秀的文章，考察了瑞典的经济史。在探讨这篇文章的重点之前，我先
进行简要的复述。
卡尔森写道：
“瑞典由于采取自由市场政策，成功避免战争，加上人民的智慧，于1870年至1950年间
成为了世界上人均收入增长最快的国家，也成为了发达国家的一员。”
确实，由于二战的中立政策，瑞典并没有遭受空袭及入侵。这保全了瑞典的工业。这个

It can be divided by 3 triangular parts, centered at (1/3,2/3).
