前半句话“To store a collection of values in sorted order”是说要把数据
sorted地存到某个数据结构中去；后半句“where you expect the collection to be
continuously modified”说以后要对这个数据结构中的数据continously modify。
insert的时候，Binary search tree比linked list快是显然的，但是continous

modification是大量的话，应该选择linked list。
不过，题目模糊的地方是，没有说清楚所谓的modify collection是modify什么，
modify的东西是不是要re-sort？

modified = false；
从start point开始由内向外一圈一圈计算每个节点的最小cost。每个节点要考虑8
个方向的相邻节点。如果有更短路径，modified设为true，更新cost。
}
dependent的原因是因为下一层如果有更短的路径了，上一层不知道下一层的结果。

恰恰相反，Python赋值和“传参”，在Python语言层面，都是纯粹地传引用，不是传值；
在CPython实现中，其实是传（二级）指针，只不过指针的概念没有往上暴露给Python。
比如这段python代码，a-->b传参时，传给b的就是a这个符号所指示的那个对象的引用。
def modify(b):
b[1] = 9
a = [0,1]
modify(a)
print(a[1]) # output 9
Python“传参”其实就是赋值，完完全全地等效。上述代码等效于：
a = [0,1]
b = a
b[1] = 9
print(a[1]) # output 9
第一段Python代码的大致等效的C语言代码如下：
#include
void modify(void *b) {
int **c = (int **) b;
(*c)[1] = 9;
}

PARIS—The French government said Monday that it had no reason to challenge
Monsanto Co.'s MON +0.20% license to sell a genetically modified corn in the
European Union after the country's food-safety agency ruled that a study

amine-modified microspheres. The carboxylate-modified microspheres should be

require a pH of less than about 9.0.
如果是前者，是只能用pH稍稍大于5的，还是说只要大于5都可以呢？
谢谢～ |

今年初，美国科学促进会（AAAS）和皮尤研究中心（Pew Research Center）联合公布
的一项调查显示，88％的科学家认为转基因食品可安全食用，持这一看法的公众只有37
％。报告认为差距如此之大的一个可能原因是，三分之二的公众认为科学家对转基因食
品的健康后果没有清晰认识。这就是真正的原因吗？
根据报告全文，皮尤中心给19，984名科学家发出了调查问卷，3748人（18.8%）完成了
问卷调查。其中生物医学学科背景的科学家占50%。报告没有说明50%的生物医学背景是
否能够代表科学家总体的学科构成。更大问题是在这50%的科学家人群中，有多少人的
工作是与转基因作物的研究有关，以什么样的方式相关。报告没有提供任何信息。
由于这些关键信息缺失，88%的科学家相信转基因安全的说法毫无意义。在一个没有代
