為什么結果是timeout
public?class?HelloWorld{
????public?static?void?main(String[]?args){
????????int?num?=?999;
????????int?count?=?0;
????????for(;;){
????????????count++;
????????????num?=?num?/?10;
????????????while(num>=0)
????????????????System.out.println("它是個"+count+"位的數！");
????????}
????????
????}
}

因為你無限循環了，
改為
num?=?num?/?10;if(num<=0)????System.out.println("它是個"+count+"位的數！");break;2018-04-09
public static ?void (){
System.out.println("你嗎的大雞腿，騙子");
