如何在数据上使用剪接和二进制搜索来删除和搜索

Question

我正在尝试使用剪接方法，但它无法正常工作以删除一个用户，但它正在删除2。

还想添加二进制搜索按钮，

这是二进制搜索的要求

使用二进制搜索算法替换顺序访问算法以在数组上操作。 为了实现此目的，必须对数组的数据进行排序。您可以在array.prototype.sort（）中参考一个在线示例，以了解在数组中对数据进行分类。

 function Display_Athlete() {
        var text = "<hr/>";
        for (let i = 0; i < athlete_name.length; i++) {
            text += "Athlete No - " + (i + 1) + ",  Athlete Name is  " + athlete_name[i]
                + "   and height is " + athlete_height[i] + "<br>";
        }
        document.getElementById("message").innerHTML = text;
    }

    //Created function to remove the user
    function Remove_Athlete() {
        var person = prompt("Enter the name to remove the Athlete");
        for (let i = 0; i < athlete_name.length; i++) {
            athlete_name.splice(person - 1, 1);
            athlete_height.splice(person - 1, 1);
            alert("  Athlete_name " + athlete_name + "   Athlete_height  " + athlete_height + "  is removed  ");
        }
    }

    //Create the function to find  the user 
    function Find_Athlete() {
        var person = prompt("Enter the name to Find the Athlete");
        var text = "";
        for (let i = 0; i < athlete_name.length; i++) {
            if (athlete_name[i] == person) {
                text += "Athlete No - " + (i + 1) + ",  Athlete Name is  " + athlete_name[i]
                    + "   and height is " + athlete_height[i] + "<br>";
            }
        }
        document.getElementById("message").innerHTML = text;
        if (text == "")
            alert(`${person} Invalid Athlete name`);
        return "";
    }

    function Binary_Search(){
        
    }
