解题思路:





注意事项:





参考代码:

#include <stdio.h>

#include <math.h>

int main(void)

{

int num[10];

int i, j, k, l, q, w, e, r, t, y, u, sum, x;

while (scanf("%d", &x) != EOF)

{

for (i = 0;i < 10;i++)

num[i] = pow(3, i);

for (j = 9;j <= 11;j++)

for (k = 9;k <= 11;k++)

for (l = 9;l <= 11;l++)

for (q = 9;q <= 11;q++)

for (w = 9;w <= 11;w++)

for (e = 9;e <= 11;e++)

for (r = 9;r <= 11;r++)

for (t = 9;t <= 11;t++)

for (y = 9;y <= 11;y++)

for (u = 9;u <= 11;u++)

{

sum = num[0] * j + num[1] * k + num[2] * l + num[3] * q + num[4] * w + num[5] * e + num[6] * r + num[7] * t + num[8] * y + num[9] * u;

if (sum == x)

{

printf("%d %d %d %d %d %d %d %d %d %d\n", j, k, l, q, w, e, r, t, y, u);

break;

}

}

}

return 0;
