sign(n) that takes a numeric value n. It returns -1 if n is negative, 1 if n is positive greater than zero, or 0 if n is zero.
The BMI (body mass index) is used to determine if a person's weight and height proportion is adequate. The BMI may be calculated using the following formula:
index = (weight) ÷ (height2)
Where weight should be given in kilograms and height in meters. The following table shows how different index ranges are classified:
| index range | Description |
|---|---|
| index < 20 | 'underweight' |
| 20 ≤ index < 25 | 'normal' |
| 25 ≤ index < 30 | 'obese1' |
| 30 ≤ index < 40 | 'obese2' |
| 40 ≤ index | 'obese3' |
Write a function called bmi(weight, height). It should return a string that represents the corresponding BMI
description computed from its input.
The following algorithm can be used to determine if a certain year is a leap year:
— Leap years are any year that can be evenly divided
by 4 (such as 2012, 2016, etc).
— Except if it can can be evenly divided by 100,
then it isn't (such as 2100, 2200, etc).
— Except if it can be evenly divided by 400,
then it is (such as 2000, 2400).
Write a function leap(y) that returns True if y is a leap year, otherwise returns False.
Write a function next_day(y, m, d) that given a date with a certain year y, month m, and day d, returns the date of the following day.
>>> next_day(2015, 2, 13) (2015, 2, 14) >>> next_day(2015, 2, 28) (2015, 3, 1) >>> next_day(2016, 2, 28) (2016, 2, 29) >>> next_day(2016, 12, 31) (2017, 1, 1)
Write a program that asks the user for a number of cents and computes the number of dollars (100¢), quarters (25¢), dimes (10¢), nickels (5¢), and pennies (1¢) needed to make that amount, using the largest denomination whenever possible.
For example, 247 cents is 2 dollars, 1 quarter, 2 dimes, and 2 pennies. Use // when you intend to use integer division. You do not need to write any functions other than main().
