Some years have 29 days in February, while others have 28. Ones that have 29 days are called leap years. We would like to know if a year is a leap year or not. That can be done with a simple rule: a year is a leap year if it is divisible by 4 but is not divisible by 100. Yet, years that are divisible by 400 are also considered leaps.
Given a year print Yes if it’s a leap year and No otherwise.
