#In the Gregorian calendar a year is a leap year when the number representing it is 
#divisible by 4, unless it is divisible by 100, unless it is divisible by 400. Thus 
#years such as 1996, 1992, 1988 and so on are leap years because they are divisible by 
#4 but not by 100. For century years, the 400 rule is important. Thus, century years 
#1900, 1800 and 1700 while all still divisible by 4 are also exactly divisible by 100. 
#As they are not further divisible by 400, they are not leap years. Also, you can 
#assume that there were no leap years before 1582. Write a program that asks the user 
#for a year and computes whether that year is a leap year. You can assume that the 
#input is a valid positive integer less than 4000. You don.t need to check validity of 
#the input.

#Example:
#Input 1980 Output Leap Year
#Input 1900 Output Not a Leap Year
#Input 1200 Output Not a Leap Year
#Input 2000 Output Leap Year
#Input 3000 Output Not a Leap Year 

#Solution

year=int(input("enter year "))

if(year>=1582):
	if(year%4==0 and year%100!=0):
		print(year,"Is Leap Year")
	elif(year%4==0 and year%100==0 and year%400==0):
		print(year,"Is Leap Year")
	else:
		print(year,"Is NOT Leap Year")
else:
	print(year,"Is NOT Leap Year")
