该博客介绍了一个程序设计问题，涉及将地球上的数字（0-169）转换为火星上的13进制数字，反之亦然。题目提供了输入和输出规范，并给出了样例输入和输出。解决方案是通过打表方法实现两种数字系统的相互转换。

Zero on Earth is called “tret” on Mars.
The numbers 1 to 12 on Earth is called “jan, feb, mar, apr, may, jun, jly, aug, sep, oct, nov, dec” on Mars, respectively.
For the next higher digit, Mars people name the 12 numbers as “tam, hel, maa, huh, tou, kes, hei, elo, syy, lok, mer, jou”, respectively.
For examples, the number 29 on Earth is called “hel mar” on Mars; and “elo nov” on Mars corresponds to 115 on Earth. In order to help communication between people from these two planets, you are supposed to write a program for mutual translation between Earth and Mars number systems.

Input Specification:

Each input file contains one test case. For each case, the first line contains a positive integer N (<100). Then N lines follow, each contains a number in [0, 169), given either in the form of an Earth number, or that of Mars.

Output Specification:

For each number, print in a line the corresponding number in the other language.

Sample Input:

4
29
5
elo nov
tam

Sample Output:

hel mar
may
115
13

题意

火星上的数字为13进制数，个位和十位数字分别用不同的英文单词表示，给定N个地球的数字或者火星的数字，求它们互相转化的结果。

思路

打表即可。对于任意一个给定的输入，通过判断它的第一个字符是否为数字来判断这个输入是十进制数还是十三进制数。使用getline来读取一行字符串。

代码

#include <iostream>
#include <map>
#include <string>
#include <cctype>
#include <cstdio>
#define BASE 13
using namespace std;
string digits[] = {
   
   "tret", "jan", "feb",
