1037. Find change at Hogwarts (20) time limit MS Memory limit 65536 KB code length limit 8000 B procedure StandardAuthor Chen, Yue

If you are a Harry Potter fan, you will know that the Wizarding world has its own monetary system-as Hagrid told Harry: "17 Silver Sickle (Galleon), 29 Nat (Knut) against a west, is easy." "Now, given the price Harry has to deal with and the money he pays a, your task is to write a program to calculate the change he should be looking for."

Input format:

The input gives p and a in 1 rows, in the form "Galleon.Sickle.Knut", separated by 1 spaces. Here galleon is an integer in the [0, 107] interval, sickle is an integer within the interval of [0, 17), and Knut is an integer within the [0, 29] interval.

Output format:

Output the change Harry should be looking for in a row with the same format as the input. If he does not have enough money, then the output should be negative.

Input Sample 1:

10.16.27 14.1.28

Output Example 1:

3.2.1

Input Sample 2:

14.1.28 10.16.27

Output Example 2:

-3.2.1

Difficulty: How to input three integers in A.B.C form to read successfully
Train of thought 2 difficulty: the output place, must satisfy the fixed output way

Train of thought 1: First convert P and a of 2 money to the minimum measure number, then the difference, and then converted to the form of the three-level unit representation
Train of thought 2: self-connected plus minus complement

Idea 1 Code:

Of course, the 38th line is very poor readability, but also just a few functions together, looks more complex, in fact, the content is very simple
