Task 3: Doomsday Algorithm, Take 4 Recall that a year's Doomsday is given by the equation: Doomsday-(((yr // 12) + (yr % 12) + (yr % 12) // 4) % 7 + anchor) % 7 (1) where yr is the last two digits of the year and the anchor day is an integer between 0 and 6 with0 comesponding to Sunday and 6 to Saturday. Previously we wrote a program to calculate a year's Doomsday that included the function calc.doom () We then added the ability to enter a full, four-digit year in one of our programming assignments. Now we're going to extend the algorithm so that, assuming we're only considering 1900-2099, we don't need to enter the anchor day. Instead we use the first two digits of the year to determine the anchor number. Thus, in this task Write a function set.anchor that takes as its parameter the first two digits of the year and returns a 2 if the digits are 20 and a 3 if the digits are 19. Use multiple if and return tatements Write a function main that prompts the user for a four-digit year (an integer), extracts the first two and last two digits of the year, calls set anchor which returns the anchor, calls calc.doom), and prints out the Doomsday Use the function calc.doom) that you wrote before. You should be able to copy and paste it from one Editor window into another. Anchor days for 2000-2099 are Tuesday (2) and for 1900-1999 Wednesday 3). Example results are shown below. Enter the year in four digits: 1966 2 Doomsday 1 4 Enter the year in four digits: 2019 s Doomsday-4
