java - 每次通过后如何打印剩余的数据？

Question

我正在为学校解决这个问题

"Write a binary search program that looks for the following 3 values 74, 35, 62 (Yes, I know...) )in the supplied data set. Your application should print out the remaining data after each pass. Data set: 23 27 29 31 35 39 40 41 52 66 71 74 75 90 99"

目前，我已编写了找到查找值位置的部分。我只是不知道如何在每次通过后打印出剩余的数据。请帮忙。

这是我的代码:

import java.util.Scanner;

class BinarySearchTracing{
  public static void main(String args[]){
    Scanner scan = new Scanner (System.in);
    int[] d = {23, 27, 29, 31, 35, 39, 40, 41, 52, 66, 71, 74, 75, 90, 99};
    int start = 0;
    int middle = 0;
    int end = d.length - 1;
    int location = -1;
    boolean found = false;

    System.out.println("Enter the look for value: ");
    int lookfor = scan.nextInt();
    scan.close();

    while(start <= end && found == false) {
        middle = (start + end) / 2;
        if(d[middle] == lookfor) {
            found = true;
            location = middle;
        }
        else if(d[middle] < lookfor) {
            start = middle + 1;
        }
        else {
            end = middle - 1;
        }
    }
    System.out.println(location);
  }
}

要打印两个索引之间给定数组的子数组，您可以使用 following methods 之一:

• Arrays.copyOfRange
• System.arraycopy等
