题目描述
火星人是以 13 进制计数的：
地球人的 0 被火星人称为 tret。
地球人数字 1 到 12 的火星文分别为：jan, feb, mar, apr, may, jun, jly, aug, sep, oct, nov, dec。
火星人将进位以后的 12 个高位数字分别称为：tam, hel, maa, huh, tou, kes, hei, elo, syy, lok, mer, jou。
例如地球人的数字 29 翻译成火星文就是 hel mar；而火星文 elo nov 对应地球数字 115。为了方便交流，请你编写程序实现地球和火星数字之间的互译。
输入
输入第一行给出一个正整数 N（<100），随后 N 行，每行给出一个 [0, 169) 区间内的数字 —— 或者是地球文，或者是火星文。
输出
对应输入的每一行，在一行中输出翻译后的另一种语言的数字。
样例输入
4
29
5
elo nov
tam
样例输出
hel mar
may
115
13

大佬的代码1：

void func1(int t) {
if (t / 13) cout << b[t / 13];
if ((t / 13) && (t % 13)) cout << " ";
if (t % 13 || t == 0) cout << a[t % 13];
}
void func2() {
int t1 = 0, t2 = 0;
string s1 = s.substr(0, 3), s2;
if (len > 4) s2 = s.substr(4, 3);
for (int j = 1; j <= 12; j++) {

if (s1 == b[j]) t1 = j;
}
cout << t1 * 13 + t2;
}
int main() {

getchar();

len = s.length();
if (s[0] >= '0' && s[0] <= '9')
func1(stoi(s));

大佬的代码2：
#include <map>
#include <cstring>
#include <iostream>
using namespace std;
string arrl[13] = {"tret", "jan", "feb", "mar", "apr", "may", "jun", "jly", "aug", "sep", "oct", "nov", "dec"};
string arru[13] = {"####", "tam", "hel", "maa", "huh", "tou", "kes", "hei", "elo", "syy", "lok", "mer", "jou"};
map<string,int> mapl = {{"tret",0}, {"jan",1}, {"feb",2}, {"mar",3}, {"apr",4}, {"may",5}, {"jun",6}, {"jly",7}, {"aug",8}, {"sep",9}, {"oct",10}, {"nov",11}, {"dec",12}};
map<string,int> mapu = {{"tam",1}, {"hel",2}, {"maa",3}, {"huh",4}, {"tou",5}, {"kes",6}, {"hei", 7}, {"elo",8}, {"syy",9}, {"lok", 10}, {"mer", 11}, {"jou",12}};
int main()
{
int n;
scanf("%d\n", &n);
string s;
for (int i = 0; i < n; i++)
{
getline(cin, s);
if (s[0] >= '0' && s[0] <= '9')
{
int num = stoi(s);
if(num<13) {
printf("%s\n", arrl[num].data());
} else if(num>=13 && (num%13==0)) {
printf("%s\n",arru[num/13].data());
} else {
printf("%s %s\n", arru[num/13].data(), arrl[num%13].data());
}
}
else
printf("%d\n", s.length()==3 ? mapl[s]+mapu[s]*13 : mapu[s.substr(0,3)]*13+mapl[s.substr(4,3)]);
}
return 0;
}
【注】：
- 能被13整除的只输出高位火星文（一个case）；
- 0转换成火星文输出 “tret”（一个case）；
- map可以不用，参考柳神代码；
- map可以批量赋值，但vs2008不支持！
- stoi(s) 把数字字符串转换成int输出，头文件是 #include ，但是vs2010之前的没有这个函数，OJ可；
