"简简单单"

终于学会链表了!!!

#include<bits/stdc++.h>
using namespace std;
struct A{
	int d;
	int next;
};
int main(){
    A a[105];
	int n;
	cin>>n;
	for(int i=1;i<=n;i++){
		cin>>a[i].d;
		a[i].next=i+1;
	}
	int k,ki;
	cin>>k>>ki;
	a[ki].next=n+1;
	a[n+1].next=ki+1;
	a[n+1].d=k;
	int i=1,ai=1;
	while(i<=n+1){
		cout<<a[ai].d<<" ";
		ai=a[ai].next;
		i++;
	}
    return 0;
}
