问题描述:
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: 3.2.1 10.16.27 Sample Output: 14.1.28
