This week's challenge was submitted by @AShapiro - Thanks for your contribution!
What’s your favorite flavor of ice cream? Hard to choose just one? With ranked choice voting (RCV), you don’t have to! With RCV, you can rank your favorites in order of choice.
For this week’s challenge, we have the results of a Favorite Flavors of Ice Cream poll. Build a workflow to conduct a RCV to find the voters’ favorite flavor and the total number of voting rounds. If a flavor receives more than half of the first choices, that flavor wins. If not, the flavor with the fewest first choice votes is eliminated. For voters who picked that flavor as their “Number 1”, their votes shift to their next choice. The process continues until a flavor has more than half the votes.
