Attack your opponents

If you find a ball on the map, you can throw it at your opponent. Each ball has a coding challenge attached to it. You can only throw the ball if you provide the correct answer to the challenge. If you hit your opponent (target) then you gain 1 point while your opponent loses 1. If your opponent also provide the correct answer to the same challenge, then the ball bounces back and hits you. In order to win, you should try to solve as many challenges as possible. You can develop more advanced strategy such as remembering which opponent has solved which challenge, so that you don't attempt to attack with another ball with the same challenge attached.

Refer to Create your first Python CodeVille Program and Create your first Java CodeVille Program for complete code samples.

In order to complete the challenges, define a new class first:

Python

class Solutions:
    def __init__(self):
        pass

Java

public class Solutions {
}

It's important for this class to be public. To create a new class in IntelliJ, click "File" menu, then "New" => "Java Class".

Then create an object and pass to the game object:

Python

game = CodeVille(Solutions())

Java

CodeVille c = new CodeVille(new Solutions());

To complete each challenge, you need to add a new function to your class. The function name is constructed from the description field, and it has to accept a list of arguments matching the arguments field. In Python, the arguments and return value can be number, string or array of them. In Java, they can be int, double, String or array of them. Here are examples for the above two challenges:

Python

class Solutions:
    def __init__(self):
        pass

    def find_smaller(a, b):
        # return smaller value
        pass

    def find_max(numbers):
        # find the largest in a list
        pass

Java

public class Solutions {
    int findSmaller(int a, int b) {
        // return smaller of a and b
    }

    int findMax(double[] numbers) {
        // return the largest in array
    }
}

The program output will tell you if you are missing any functions.

Warning: method not defined: find_largest(self, list)
