pat 甲级 1082 Read Number in Chinese (25 分)

这道题bug改了巨久，看睛神和柳神都是分组处理的，想要试试不分组的，总算AC了

大致思路是先对字符串进行预处理

把负号先输出，然后删掉

把第一个有效字符前的所有零全都删掉

以上

然后对这个字符串一个个遍历

在输出前我们要先知道数字用中文翻译的规则，比如没有零一千对吧

然后读字符串里的字符，记录它的位置，比如亿位我记为8（从0开始）

读到非零的字符，输出，再根据它所在的位数输出它的位

读到零了，要注意Yi和Wan都得输出，然后记录连续有几个0，注意如果连续0大于等于3个，那么Wan就不必输出了。然后我们回到非零的那块

非零补充：如果它前面是0，那就多输出一个ling，Qian不能输出

下面是原题：

1082 Read Number in Chinese (25 分)

Given an integer with no more than 9 digits, you are supposed to read it in the traditional Chinese way. Output Fu first if it is negative. For example, -123456789 is read as Fu yi Yi er Qian san Bai si Shi wu Wan liu Qian qi Bai ba Shi jiu. Note: zero (ling) must be handled correctly according to the Chinese tradition. For example, 100800 is yi Shi Wan ling ba Bai.

Input Specification:

Each input file contains one test case, which gives an integer with no more than 9 digits.

Output Specification:

For each test case, print in a line the Chinese way of reading the number. The characters are separated by a space and there must be no extra space at the end of the line.

Sample Input 1:

-123456789

Sample Output 1:

Fu yi Yi er Qian san Bai si Shi wu Wan liu Qian qi Bai ba Shi jiu

Sample Input 2:

100800

Sample Output 2:

yi Shi Wan ling ba Bai
