第三个嫌我答案太长

#include<iostream>
using namespace std;
int main()
{
	int  num = 0;
	cin >> num;
	int arr[10000];
	arr[0] = num;
	int i = 1, a = 1;//a��ͳ��������Ԫ�صĸ���
	while (num != 0)
	{
		if (num % 2 == 0)
		{
			num /= 2;
			arr[i] = num;
			a++;
			i++;

		}
		else if (num % 2 != 0)
		{
			num = 3 * num + 1;
			arr[i] = num;
			a++;
			i++;
		}
		if (num == 1)
		{
			break;
		}
	}
	for (int i = a - 1; i >= 0; i--)
	{
		cout << arr[i] << " ";
	}

}
