Please write a PL/SQL program to check whether a year is a leap year. Please print out whether it is a leap year. You can use a variable to store the year your are checking. Here are the rules to decide a leap year: a year that is not divisible by 4 is not a leap year a year is divisible by 4 but not by 100 is a leap year a year is divisible by 100 but not by 400 is not a leap year a year that is divisible by 400 is a leap year. Hint: mod(a, b) returns a mod b (remainder of a divided by b).
