Celsius Temperature Table The formula for converting a temperature from Fahrenheit to celsius is C = 5/9 (F - 32) where F is the Fahrenheit temperature and C is the celsius temperature. Write a function named celsius that accepts a Fahrenheit temperature as an argument. The function should return the temperature, converted to Celsius. Demonstrate the function by calling it in a loop that displays a table of the Fahrenheit temperatures 0 through 20 and their celsius equivalents
