js 写的几个算法

var log = console.log;

let arr = [23,45,23,46,1,100,14];

function Figure(){

}
Figure.prototype = {
    /*简单递归*/
    factorial:function(number){
        if(number==1){
            return number;
          }else{
            return (number)*this.factorial(number-1);
          }
    },
    /*冒泡排序*/
    bubbling(arr){
      for(var j=0;j<arr.length-1;j++){
        for(var i=0;i<arr.length;i++){
          if(arr[i]>arr[i+1]){
                var  tepm = arr[i]
              arr[i] = arr[i+1];
              arr[i+1] = tepm;
          }
        }
      }
      return arr;
    },
    //找到数组中最大的三个 
    findMax3(){
      var tempArr = [arr[0],arr[1],arr[2]];
      for(var i=0;i<arr.length;i++){
        var min = this.findMin(tempArr);
        if(arr[i]>min[0]){
