Day 26: Nested Logic

Task 
Your local library needs your help! Given the expected and actual return dates for a library book, create a program that calculates the fine (if any). The fee structure is as follows:

1. If the book is returned on or before the expected return date, no fine will be charged (i.e.: .
2. If the book is returned after the expected return day but still within the same calendar month and year as the expected return date, .
3. If the book is returned after the expected return month but still within the same calendar year as the expected return date, the .
4. If the book is returned after the calendar year in which it was expected, there is a fixed fine of .

Input Format

The first line contains  space-separated integers denoting the respective , , and  on which the book was actually returned. 
The second line contains  space-separated integers denoting the respective , , and  on which the book was expected to be returned (due date).

Constraints

Output Format

Print a single integer denoting the library fine for the book received as input.

Sample Input

9 6 2015
6 6 2015

Sample Output

45

Explanation

Given the following return dates: 
Actual:  
Expected: 

Because , we know it is less than a year late. 
Because , we know it's less than a month late. 
Because , we know that it was returned late (but still within the same month and year).

Per the library's fee structure, we know that our fine will be . We then print the result of  as our output.

풀이

다른 사람 discussion을 확인해보니 day, month, year 각각 nextInt로 받아와도 된다.

각각 int형으로 받아와서 비교해주는게 좀 더 보기에는 편할 거 같다.
