My datafile (you don't see it!) has 14 columns that correspond to medical measurements of a person (blood pressure, height, weight, etc.) The measurements are in different units. Which of the following is true? A. It doesn't matter! Any learning algorithm will take care of it automatically.
B. Remove all the measurements that are not in inches.
C. Convert all measurements to either inches or centimeters (it doesn't matter which!) and then you don't have to think about it.
D. Use the z score to rescale all features to have a mean of 0 and standard deviation of 1.

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.
