2018爱奇艺Java开发实习生面筋

总共15道选择题，3道编程题。我感觉选择题是比较难的。

第二题.jpeg

这是第二道编程题.
我的解法如下(AC)：

  public static void main(String[] args) {  
     Scanner in = new Scanner(System.in);  
     while (in.hasNextInt()) {//注意while处理多个case  
       int a = in.nextInt();  
       int b = in.nextInt();  
       int c = in.nextInt();  
       int max = Math.max(a,Math.max(b,c));  
       int min = Math.min(a,Math.min(b,c));  
       int mid = 0;  
       int count = 0;  
       if(a != max && a != min){  
         mid  = a;  
       }else if(b != max && b != min){  
         mid = b;  
       }else{  
         mid = c;  
       }  
       if(mid + 1 == max){  
         count = (max - min - 1)/2 +1;  
       }else if((max - mid)%2 == 0){  
         count += (max - mid)/2;  
         if((max - min)%2 == 0){  
           count += (max - min)/2;  
         }else{  
           count +=(max - min)/2 + 2;  
         }  
       }else if((max - mid)%2 != 0){  
         count += (max - mid)/2;  
         if((max - min)%2 != 0){  
           count += (max - min)/2 +1;  
         }else{  
           count += (max - min)/2 +2;  
         }  
       }  
       System.out.print(count);  
     }  
   }  ```
