因为这种点击的可能数目是很小的，可以把所有的用个某种alphabet表示，比如, welc
ome->a Hello->b, books->c
这样把整个log过一遍，每个用户分开，每个用户的连续点击用array表示，比如zhang:
abceafe
Li: acdef
Wang: abc
After that,根据这个表生成一个trie,节点的value记录发生的次数。比如abceafe,则在
节点 c,e,a,f,e（都是可能的连续三的点击）上都要记录1，然后处理下一个用户，把相
应的节点value值加1。
到最后traverse这个trie,找出最大的value的节点，然后从它往加上parent和grand pa
rent就是最大的连续点击的三连击。可以拓展到3以上的。 |

What are the pros and cons here?

If a girl has kindness from the eyes, that's at least average from me. If
she has the power of giving, she will be top.
If you check her "early picture", you could find some kindness. But from
the lastest pictures, what did you see from her eyes?
Eyes don't lie.
P.S. I don't mind people call me fugly or ugly or shitty or prevert. My parents, as professors, always welc |

SAN FRANCISCO (AP) -- Google Inc. will shift its search engine for China off
the mainland but won't shut it down altogether, and it will maintain other
operations in the country. It's an attempt to balance its stance against
censorship with its desire to profit from an explosively growing Internet
market.
On Monday afternoon, visitors to Google.cn were being redirected to Google's
Chinese-language service based in Hong Kong. The page said, according to a

2013年12月17日，美国内科协会年鉴杂志发表了一篇编辑文章，题目就叫做“够了！不
要在维生素和矿物质补充剂上浪费钱了（Enough Is Enough: Stop Wasting Money on
Vitamin and Mineral Supplements）。”编辑文章代表着该杂志的观点。美国内科年鉴
是美国医师协会的官方杂志，是一份严肃严谨很有权威性的学术杂志，居然用了这样一
个洛杉矶时报风格的抢眼的标题作为编辑文章，目的不言而喻：就是要吸引媒体的广泛
关注，将这个美国医师协会的观点传播给普通大众。因为维生素和矿物质补充剂是在超
市随手可买的商品，普通大众是最大的消费人群。
分析这个文章之前，先来介绍一下这几位作者。Eliseo Guallar医学和药学博士，Lawr
ence J. Appel医学博士和Edgar R. Miller医学博士均来自于约翰霍普金斯医学院Welc
h疾病预防中心，Saverio Stranges医学博士来自英国Warwick大学医学院，Cynthia Mu
lrow医学博士是该杂志的高级副主编，均为医学界翘首。

face, and presses a button.)
