非常基础的方式

解题思路:

注意事项:

参考代码:

#include <stdio.h>

int main()

{

int i,j;

int arr[100] = { 0 };

for (i = 0; i < 100; i++)

{

scanf("%d", &arr[i]);

if (arr[i] == 0)

break;

}

int sum = 0;

for (j = 0; j < i ; j++)

{

int sum = 0;

int remain = arr[j];

while (remain != 1 && remain != 0)

{

sum += remain / 3;

remain = remain % 3 + remain / 3;

if (remain == 2)

{

sum += 1;

break;

}

}

arr[j] = sum;

}

for (j = 0; j < i ; j++)

{

printf("%d\n", arr[j]);

}

return 0;

}
