华为：空瓶子

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        int arr[] = new int[n];
        for (int i = 0; i < n; i++) {
            arr[i] = sc.nextInt();
            arr[i] = resolve(arr[i]);
        }

        for (int i = 0; i < n; i++) {
            System.out.println(arr[i]);
        }
    }

    public static int resolve(int a) {
        int sum = 0;//总共可以换的汽水数量
        int kp = a;//空瓶数量
        while (kp >= 3) {
            sum = sum + kp / 3;
            kp = kp / 3 + kp % 3;
        }
        if (kp == 2) {
            sum=sum+1;
        }

        return sum;
    }
}

问题在于怎么读：程序显示一直运行
