将输入的三个数字按从小到大的顺序输出

将输入的三个数两两比较，将较大的值交换到后面，分别比较ab、bc、ab即可。

```javascript
   <script>
           document.write(judgeThem(3,2,1));
           function judgeThem(a,b,c){            
           var temp;            
           if(a > b){                
           	temp = a;
              	a = b;   
                b = temp;
                }
                if(b > c){	
                temp = b;
                b = c;
                c = temp;            
                }
                if(a > b){
                temp = a;
                a = b;   
                b = temp;
                }
                return(a+ "&nbsp" + b + "&nbsp" + c);        }    
  </script>
