sentence numbers in which each occurrence appeared.
a. a {2:1,1}
b. all {1:1}
c. alphabetical {1:1}
d. an {2:1,1}
e. appeared {1:2}

Although the iPhone 4 has proven to be a Consumer Reports outcast, the
device's successor, the iPhone 4S, has been recommended by the organization.
"The Apple iPhone 4S is among the recommended models in our newly updated
Ratings of smart phones," Consumer Reports announced today. "Apple's newest
smartphone performed very well in our tests, and while it closely resembles
the iPhone 4 in appearance, it doesn't suffer the reception problem we found
in its predecessor in special tests in our labs."
Consumer Reports stirred up a controversy last year when it announced that
it could not recommend the iPhone 4 to its subscribers. The organization
said at the time that when users touched the gap on the lower left side of
the device, "the signal can significantly degrade enough to cause you to
lose your connection altogether if you're in an area with a weak signal."
Apple acknowledged that flaw soon after the iPhone 4 launched last year, and
offered owners a free case to address the problem. However, Consumer
Reports still refused to recommend the iPhone 4, despite its belief that the
device was a fine option for consumers on most other fronts. "Putting the
onus on any owners of a product to obtain a remedy to a design flaw is not
acceptable to us," Consumer Reports said at the time.
In its testing, Consumer Reports found that there is no reception issue when
users hold the iPhone 4S. The organization said that the iPhone 4S beat out
the iPhone 4 in other areas as well thanks to its dual-core processor and
improved camera. All told, the iPhone 4S received a score of 75 from
Consumer Reports, besting the iPhone 4's 73.

美国致力于拥护消费者权益的知名杂志《消费者报告》（Consumer Reports）日前宣布
，他们向广大消费者推荐iPhone 4S，并认为这部苹果的新一代手机并没有出现像上一
代iPhone一样的信号接收问题。
《消费者报告》称，他们按照惯例在实验室当中对iPhone 4S进行了测试，发现苹
果已经解决了在iPhone 4身上出现的信号问题。另外，他们还发现苹果新推出的8GB
iPhone 4依然存在着信号问题。
去年，《消费者报告》曾经一度把iPhone 4评为市面上最好的智能手机，不过后来
他们发现了iPhone 4会出现信号问题，随之改变了立场，发出不向消费者推荐使用
iPhone 4的声明。

(A)出错，(B)能通过。
如果硬要用var，有办法修补(A)吗？
(A) var name string, age int = "猪八戒", 500
(B) name, age := "猪八戒", 500

这还不简单。
用一个hashtable存储，key是单词，values是arraylist，这个arraylist的第一个位置
存放次数，后面依次存放出现的句子数。
顺序读取文件，一个个句子一个个词的扫描。每扫描到一个词，加入到hashtable里或
者改变对于的value里面的值。
要是在java里，可以用treemap代替hashtable来存储，因为treemap的key是排序的。

貌似用格式(A)，只能定义同一类型的多个变量，比如
var 大徒弟, 二徒弟 string = "孙悟空", "猪八戒"
