Given a year , Judge whether this year is a leap year .
When one of the following conditions is satisfied , This year is a leap year ：
The year is 4 Instead of 100 Multiple ;
The year is 400 Multiple .
Other years are not leap years . Input format input contains an integer y, Represents the current year . Output format output one line , If a given year is a leap year , The output yes, Otherwise output no.
explain ： When the question specifies that you output a string as the result （ For example, this topic yes perhaps no, You need to strictly follow the case given in the test , Wrong case will not score . The sample input 2013 Sample output no The sample input 2016 Sample output yes Data scale and agreement 1990 <= y <= 2050.
y = int(input())if (y%4 == 0 and y%100!=0) or y%400 ==0: print('yes')else: print('no')
