  int i=0, j=0, n=0, min=0, max=0,sum=0;
  int a[7];
  for (i = 0; i < 7; i++)
  scanf_s("%d,", &a[i]);
  if (min>a[i])
  {min = a[i + 1];
  a[i] = min;
  a[i] = a[i + 1];}
  if (max < a[j])
  {max = a[j - 1];
  a[j] = max;
  a[j] = a[j - 1];}
  {min = a[1];
    max = a[7];}
  
  sum = a[2] + a[3] + a[4] + a[5] + a[6];
  n = (sum / 5);
  printf("%5.2f",(float) n);
  
  return 0;
