ikun必用

在dext.top代码的基础下改编的（没开玩笑真能用）

#include<bits/stdc++.h>
#define ikun int
#define jinitaimei for
#define niganmahahahaiyou return
using namespace std;
ikun kun=1;
ikun kunge=2;
ikun kunkun=3;
ikun caixukun=0;
ikun main(){
	ikun cai;
	cin>>cai;
	ikun xu[cai]; 
	xu[kun]=kun;
	xu[kunge]=kunge;
	jinitaimei(ikun ji=kunkun;ji<=cai;ji++){
		xu[ji]=kun;
		jinitaimei(ikun zhiyin=kun;zhiyin<=ji/kunge;zhiyin++)
			xu[ji]+=xu[zhiyin];
	}
	cout<<xu[cai];
	niganmahahahaiyou caixukun;
}
