需要为我的程序删除 BST 操作

Question

package com.Binary_Search_Tree;

public class HackerRank 
{
    HackerRank left , right;
    int data;
    
    public HackerRank(int data)
    {
        this.data = data;
    }
    
    public void insert(int value)
    {
        if (value <= data) 
        {
            if (left == null) {
                left = new HackerRank(value);
            }else {
                left.insert(value);
            }
        }
        else 
        {
            if (right == null) {
                right = new HackerRank(value);
            }else {
                right.insert(value);
            }
        }
    }

}

In my delete operation I can go to the value but I can not make it null because its an integer value. do anyone can suggest something better which fits my code.

您可以将data字段，因为它是去除left和right的引用以及其他引用该点要删除应该足够的对象。
