我的源代码如下:
#include <iostream.h>

long fac[10] = { 1,1,2,6,24,120 ,720,5040,40320,362880};

int main()
{
	long n;
	int i;

	cin>>n;

	while ( n != -1 ) 
	{
		i = 9;
		while (  n >= 0 && i >= 0 )
		{
			if ( fac[i] <= n ) 
				n = n - fac[i];
			i --;
		}

		if ( n == 0 )
			cout << "YES";
		else
			cout << "NO";
		cout << endl;

		cin>>n;
	}

	return 0 ;
}

• Re:怎么会出现output limit exceed呢?不是遇-1就结束吗? (465) xiaoha 2005-01-05 14:42:19
