自己编写一个find查找函数：

static bool find(vector<int> bn_vec, int an){
	for(vector<int>::iterator bn_vec_it = bn_vec.begin(); bn_vec_it != bn_vec.end(); bn_vec_it++){
		if( *bn_vec_it == an )
			return true;
	}
	return false;
}

vector<int> bn_vec;
bn_vec.push_back(2);
//...
int an = 1;

while( find(bn_vec, ++an) );
