超直觀寫法：塞爆for迴圈
int main()
{
string nums;
string en_alpha = "ABCDEFGHJKLMNPQRSTUVXYWZIO"; //按數字排序
string nums_list = "0123456789";
short sum = 0;
cin >> nums;
for (short i = 0; i < 26; i++)
{
if (nums[0] == en_alpha[i])
{
sum += (i + 10) / 10 + (i + 10) % 10 * 9;
for (short j = 1; j < 10; j++)
{
for (short k = 0; k < 10; k++)
{
if (nums[j] == nums_list[k])
{
sum += k * (9 - j);
if (9 - j == 0)
sum += k;
}
}
}
if (sum % 10 == 0)
cout << "real" << endl;
else
cout << "fake" << endl;
break;
}
}
if (sum == 0)
cout << "fake" << endl;
return 0;
}
