Problem description

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 ：

1. The year is 4 Instead of 100 Multiple ;

2. 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.

The sample input

2013

Sample output

yes

The sample input

2016

Sample output

no

Data scale and agreement

1990 <= y <= 2050

Implementation code

y=int(input())
if y%400==0:
print('yes')
else:
if y%4==0:
if not(y%100==0):
print('yes')
else:
print('no')
else:
print('no')

matters needing attention

Leap year judgment is transformed into a mathematical problem to meet 1. The year is 4 Instead of 100 Multiple ;2. The year is 400 Multiple . The problem of two conditions .
Pay attention to case when outputting .
