1058 A+B in Hogwarts

发表于 更新于 分类于 ，

题目

If you are a fan of Harry Potter, you would know the world of magic has its own currency system -- as Hagrid explained it to Harry, "Seventeen silver Sickles to a Galleon and twenty-nine Knuts to a Sickle, it's easy enough." Your job is to write a program to compute A+B where A and B are given in the standard form of Galleon.Sickle.Knut (Galleon is an integer in [0,107], Sickle is an integer in [0, 17), and Knut is an integer in [0, 29)).

Input Specification:

Each input file contains one test case which occupies a line with A and B in the standard form, separated by one space.

Output Specification:

For each test case you should output the sum of A and B in one line, with the same format as the input.

Sample Input:

1
3.2.1 10.16.27

Sample Output:

1
14.1.28

题意

又是一道花里胡哨的题目,给你两个分成三个数的字符串,让你通过"霍格沃兹"进制来计算他们的和:最后一个数是29进制,中间那个数是17进制,第一个数是10进制.

思路

这道题没什么好说的,就是进制算就完事了,尤其是这个数只有3份,甚至都不用循环,直接写就行了.
