SzNOI c002 约瑟夫循环

这题题目没怎么弄清，不知道循环旋转的时候从哪开始，也就不想了，写个简答的约瑟夫循环

#include<iostream>
using namespace std ;
struct LinkNode {
	LinkNode  *link ;
	int data ;
} ;//dingyi 

void CreatList (LinkNode *first,int number) {
//	LinkNode *first ;*first ;
	LinkNode *current = first ;
//	int number ;
//	int m1 ;
//	int m2 ;
//	cin >> number ;
//	cin >> m1 ;
//	cin >> m2 ;
	for(int i =1 ;i < number  ;i++ ){
		//create
		current->data = i ;
		LinkNode *newNode =new LinkNode ;
		current->link = newNode ;
		current = newNode ;
	}
	current->data = number  ;
		current->link = first ;
}
void print(LinkNode *first ) {
		//int i= 0;
		while (first != NULL) {
			cout << first ->data << endl;
			//i++;
			first = first->link ;

		}
		//cout <<i;
	}
void Josephus (LinkNode *first,int number,int m1 ) {
	LinkNode *pre =NULL ;
