Read Number in Chinese (25)

Posted 2021-02-04 kuroko-ghh

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".

 

输入描述:

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

输出描述:

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.

 

输入例子:

-123456789

 

输出例子:

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