Suppose that we have the following three tuples in a legal instance of a relation schema s with three attributes abc (listed in order): (1,2,: 3), (4,2,3), and (5,3,3).
1. which of the following dependencies can you infer does not hold over scherna s?
(a) a > 13, (b) be > a, (c) 13 > c 2.
can you identify all y dependencies that hold over s?

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.
