为什么输入-15 2答案不正确呢

借个楼，我顺便想问问这题给的数据是不是太小了ORZ <br>
以下这种暴力解法居然也可以AC
```
语言：C
#include <stdio.h>
#include <math.h>
char chara_form[20]= "0123456789ABCDEFGHIJ";
int main()
{
int num,base;
scanf("%d %d", &num, &base);
int convert[20]={0};
int i,j;
for(i=0;i<(1<<20);i++)
{
int _i=i;
for(j=0;_i>0;j++)
{
convert[j] = _i%(-base);
_i = _i/(-base);
}
int sum=0;
for(;j>=0;j--)
{
sum = sum + convert[j]*pow(base,j);
}
if(sum==num) goto output;
}
goto END;
output:;
printf("%d=", num);
i = 19;
while(convert[i]==0)
{
i--;
}
for(;i>=0;i--) printf("%c", chara_form[convert[i]]);
printf("(base%d)", base);
END: return 0;
}
```

@[apassbydreg](/space/show?uid=169971) 暴力本来就能A
2^20随便过

@[apassbydreg](/space/show?uid=169971) 但是n其实可以很大啦，毕竟正解是Log的
