a tiny quiz game.

Time to build a real game! Your quiz asks three questions, one after another. It reads each answer from the keyboard, keeps score, and tells the player how they did at the end.

The questions and answers live in two arrays, side by side. The method `isRight` takes a guess and the real answer, and returns `true` or `false`. A `for` loop counts through the indexes, so `questions[i]` and `answers[i]` always match up.

Be kind to your player: `MARS`, `mars` and `Mars` with extra spaces should all count as right. Fill in each `____`, run it, then play your own quiz.

Your program

import java.util.Scanner;
public class Main {
    static boolean isRight(String guess, String answer) {
        return guess.____().____().equals(answer.toLowerCase());
    }

public static void main(String[] args) {
        Scanner keyboard = new Scanner(System.in);
        String[] questions = {"What is 7 x 6?", "Which planet is red?", "How many legs does a spider have?"};
        String[] answers = {"42", "Mars", "8"};
        int score = 0;
        for (int i = 0; i < questions.length; i++) {
            System.out.print(questions[i] + " ");
            String guess = keyboard.nextLine();
            if (isRight(guess, ____)) {
                System.out.println("Correct!");
                score = ____;
            } else {
                System.out.println("Not quite. It was " + answers[i] + ".");
            }
        }
        System.out.println(String.format("You got %d out of %d!", ____, questions.length));
        if (score == questions.length) {
            System.out.println("Perfect! You are a quiz champion!");
        }
    }
}

Fill in every ____ then run the checks.
