（1）、源代码：

#include <iostream>

#include <stack>

#include <cmath>

using namespace std;

 

void change(int data){

                stack<int>s;

                if(0 == data)

                                cout << "0";

                else if(data < 0){

                                int temp = abs(data);

                                while(0 != temp){

                                                s.push(temp%6);

                                                temp /= 6;

                                }

                                cout << "-";

                                while(!s.empty()){

                                                cout << s.top();

                                                s.pop();

                                }

                }

                else{

                                while(0 != data){

                                                s.push(data%6);

                                                data /= 6;

                                }

                                while(!s.empty()){

                                                cout << s.top();

                                                s.pop();

                                }

                }

                cout << endl;

}

 

int main(){

                int i, n, num;

                cin >> n;

 

                for(i = 0; i < n; i++){

                                cin >> num;

                                change(num);

                }

    return 0;

}

  

（2）、解题思路：略

（3）、可能出错：注意0和负数。
