Enter a year and determine whether the year is a leap year or not. A leap year is a noncentury year that is divisible by 4. A century year is a year divisible by 100, such as 1900. A century year, which is divisible by 400, such as 2000, is also a leap year. Hint: If a year is divisible by 4 and is not divisible by 100 or divisible by 400, it is a leap year. (Duration: 30 min)
