实现代码:
#include <iostream>
#include <unistd.h>
using namespace std;
struct Node
{
int value;
struct Node *next;
};
class Joseph
{
public:

{

head->next = NULL;
insert();
kill();
}
~Joseph(){delete head;}
void print();
void insert();
void kill();
private:
struct Node *head;
int num;
};
void Joseph::print()
{
if(NULL == head->next)
{
return;
}
struct Node *temp = new(struct Node);
temp->next= head->next;
while(temp->next->next != head->next)
{
cout << temp->next->value << " ";

}
cout << temp->next->value << endl;
}
void Joseph::insert()
{
for(int i = 1; i <= num; i++)
{
struct Node *node = new(struct Node);
node->value = i;
if(NULL == head->next)
{
head->next = node;
node->next = node;
}
else
{

while(temp->next->next != node->next)
{

}
}
}
void Joseph::kill()
{
struct Node *temp = new(struct Node);
temp->next = head->next;
struct Node *kill = new(struct Node);
while(num-- > 1)
{

}
