爆零代码如下：

#include <iostream>
#include <cmath>
#include <cstring>
using namespace std;
int n,num=0,ans=0;
int main() {
    freopen("apple.in", "r", stdin);
    freopen("apple.out", "w", stdout);
    scanf("%d",&n);
    while(n){
        ans++;
        if(n%3==1&&num==0) num=ans;
        if(n%3==0) n-=n/3;
        else n-=n/3+1;
    }
    printf("%d %d \n",ans,num);
    return 0;
}

谢谢救助！！！
