题目内容

输入一个正整数,并做以下运算:如果为偶数,除以2;如果为奇数,乘3加1。得到的结果再按上述要求运算,直到最后的结果为1,经过多少次这样的运算才得到数1。public 1Test{public 2void main(string[] args){System.out.println("请输入一个正整数:");Scanner sc=new Scanner(System.in);int num =3;int count = 0;while (num != 1){if (4){num = num / 2;}else{num=num*3+1;}5;}System.out.println("次数为:" + count);}}
