参考代码:

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        int n = scanner.nextInt();

        int cocktailCases = scanner.nextInt();

        int cocktailEffectiveCases = scanner.nextInt();

        for (int i = 1; i < n; i++) {

            int cases = scanner.nextInt();

            int effectiveCases = scanner.nextInt();

            double cocktailRate = (double) cocktailEffectiveCases / cocktailCases;

            double rate = (double) effectiveCases / cases;

            if (rate - cocktailRate > 0.05) {

                System.out.println("better");

            } else if (cocktailRate - rate > 0.05) {

                System.out.println("worse");

            } else {

                System.out.println("same");

            }

        }

    }
