# Write a method leap_year?. It should accept a year value from the user, check whether it's a leap year, and then return true or false. Note: a century year, like 1900 and 2000, is a leap year only if it is divisible by 400.

def leap_year?(year)
  year % 400 == 0 || year % 100 != 0 && year % 4 == 0
end
