java - 科拉兹序列 : Which number is the biggest?

Question

所以我已经为 Collat​​z 序列编写了代码，但我希望能够识别并打印出序列中出现的最大数字。这是我的代码:

import java.util.Scanner;

public class CollatzSequence {
    public static void main(String[]args) {
        Scanner keyboard = new Scanner(System.in);
        int n,ts = 0;

        System.out.print("This is the Lothar Collatz Sequnce. Please enter the starting number.\n>");
        n = keyboard.nextInt();

        do {
            if (n % 2 == 0) {
                n = n / 2;
                System.out.println(n);
            }
            else {
                n = n*3 + 1;
                System.out.println(n);
            }
        ts++;
        }
        while (n != 1);       
        System.out.println("Terminated after "+ts+" steps.");

        }
    }

创建一个名为max的变量。将其初始设置为等于n。在每个步骤中，检查是否 n > max，如果是，则将 max 设置为 n。
