本文介绍了一种算法，用于处理用空格、逗号或句号分隔的英文单词字符串，通过程序拆分单词并统计数量。适用于多组输入数据，包括字符串长度限制与单词数量限制。

description

<span style="font-family:Arial, Helvetica, sans-serif;"><span style="white-space: normal;">有一个用空格( )、逗号（，）或是句号（.）分隔的许多英文单词组成的字符串（分隔的空格可以是多个）。请编写程序将这些单词分开并输出。

要求，在main函数中完成数据的输入。在子函数中完成拆分单词及统计个数。
提示：可以将待拆分的字符串作为参数进行拆分。拆出的单词可以用指针数组分别指向，并可以在子函数中输出（这样就不必把用指向分出单词的指针数组作为参数了）。子函数返回拆出的单词的个数，个数可以在main中输出。</span></span>

input

<span style="font-family:Arial, Helvetica, sans-serif;"><span style="white-space: normal;">put
  输入的数据可以有多组，首先第一行输入一个整数n，接下来是n行，每行是用空格、逗号、句号分隔的字符串，字符串的长度少于1000个字符，拆出的单词的个数少于300个。</span></span>

output

<span style="font-family:Arial, Helvetica, sans-serif;"><span style="white-space: normal;">对于每组数据，首先 输出每行字符串分出的单词(分出的各个单词用空格分隔)。接下来输出分出的单词的个数。</span></span>
