# Write a function

# We add a Leap Day on February 29, almost every four years. The leap day is an extra, or intercalary, day and we add it to the shortest
# month of the year, February. 
# In the Gregorian calendar three criteria must be taken into account to identify leap years:
# The year can be evenly divided by 4;
# If the year can be evenly divided by 100, it is NOT a leap year, unless;
# The year is also evenly divisible by 400. Then it is a leap year.

# This means that in the Gregorian calendar, the years 2000 and 2400 are leap years, while 1800, 1900, 2100, 2200, 2300 and 2500 are NOT
# leap years.

# Task 
# You are given the year, and you have to write a function to check if the year is leap or not.
# Note that you have to complete the function and remaining code is given as template.

# Input Format
# Read y, the year that needs to be checked.

# Constraints
# 1900 <= y <= 10**5

# Output Format
# Output is taken care of by the template. Your function must return a boolean value (True/False)
