//     case 'k':
//     case 'A':
//       count--;
//       break;
// }
// var action = "Hold";
// if (count > 0){
//   action = "Bet";
// }

//   // Only change code above this line
// }
 switch(card) {
    case 2:
    case 3:
    case 4:
    case 5:
    case 6:
      count++;
      break;
    case 10:
    case "J":
    case "Q":
    case "K":
    case "A":
      count--;
      break;
  }

  var holdbet = 'Hold'
  if (count > 0) {
    holdbet = 'Bet'
  }

  return count + " " + holdbet;
}

cc(2); cc(3); cc(7); cc('K'); cc('A');
