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。

输入格式：

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。

输出格式：

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。

输入样例： 
4
29
5
elo nov
tam
输出样例： 
hel mar
may
115
13
