Heros and Villains

BJ’s sister is remodeling his nephew’s room. It is a super hero themed. He has been getting into comic books and super heros ever since he met Spiderman. He’s asked us to build him a way to look up superheros and the villians they’ve fought and defeated.

The Challenge

In this challenge we’ll be searching and sorting lists of objects. We have a list of heros with their villians, the last time they fought, the number of times fought, and the number of wins.

Creating a Test Case

No matter the level you choose to work with write a test case before you start your code. Then write just enough code to pass the test. Once you have passing code refactor to pass other test cases.

Level 1

Starting off in level 1 we need to be able to tell if a hero has fought a villian. Have the user input the hero’s name and the villain and then let the user know if that hero has faced that villian.

A Step Further

Going a step further allow the user to enter a hero and then produce a list of the villians they have faced and order them by the most recent time they have fought.

Level 2

For level 2 we want to allow the user to enter a villian’s name and return a list of heros they have faced.

A Step Further

Going a step further order the list of heros by number of times the villian has fought the hero. Include the number of times the villian won.

Level 3

With the information provided if given a villian determine which hero is the most likely to win in a fight with that villian.

A Step Further

Going a step further, predict the chances of hero and villian winning when the user provides a hero and a villian.
