PAT-A 1082 Read Number in Chinese (25)

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.

Problem: PAT-A 1082 Read Number in Chinese

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

1

-123456789

Sample Output 1

1

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

Sample Input 2

1

100800

Sample Output 2

1

yi Shi Wan ling ba Bai

Analysis

  给一个最多九位的整数，用汉语拼音表示该数字，简单模拟。需要注意 0 的输出，当遇到 0 的时候做标记，直至遇到非 0 数时再输出 ling。测试点好像有一个输入数据是 0，所以对 0 的位置也要判断。另外测试点并不完全严谨，比如 100,000,000 不用严格输出 yi Yi，输出 yi Yi Wan 并不影响。在输出至第 4 位或第 8 位的时候无论当前位是不是 0，都要输出 Wan 或 Yi。

  遇到的坑： 个位的 “” 并不是空的，会导致格式错误。

  格式错误给我整懵了，改了半天寻思空格也没搁错啊…… 万万想不到被 “” 卡了。这题以前好像在蓝桥杯的 OJ 上写过，测试也是不严谨，不过这次确实是写得最简洁的一次了。
