void perm(int list[], int k, int m)
{
    if (    )
    {
        copy(list,list+m,ostream_iterator<int>(cout," "))
        cout<<endl
        return
    }
    for (int i=k i<=m i++)
    {
        swap(&list[k],&list[i])
        (    )
        swap(&list[k],&list[i])
    }
}

以下输出正确的是（ ）

#include <iostream>
using namespace std

class Base {
public:
    void virtual Func() {
        cout << "Base" << endl
    }
}

class Derived : public Base {
public:
    void virtual Func() {
        cout << "Derived " << endl
    }
}

int main() {
    Base* pBase = new Base()
    pBase->Func()
    Derived* pDerived = (Derived*)pBase
    pDerived->Func()
    delete pBase

    pDerived = new Derived()
    pBase = pDerived
    pBase->Func()

    delete pDerived
    return 0
}

int func(int N)
{
    int cnt = 0
    for(int i=1i<=Ni++)
        for(int j=1j<=Nj+=i)
            cnt+=(i+j)
    return cnt
