PAT 乙级 1044. 火星数字(20) Java版

来源:互联网 发布:数据结构排序算法心得 编辑:程序博客网 时间:2024/05/16 01:49

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:

4295elo novtam

输出样例:
