十三张牌

有十三张牌, 将最上面的抽出来放在最下面,之后将最上面的牌抽走, 若抽走的顺序是
1 2 3 4 5 6 7 8 9 10 11 12 13 问原始的顺序是什么?

what = []

for x in range(13):
    what.append(13 - x)
    what.append(what.pop(0))

what.reverse()
print what

#include <iostream>

int main(int argc, char *argv[])
{
    int vec[13] = { 0 };

    for (int i = 0, x = -1; i < 13; ++i)
    {
        for (++x; vec[x % 13]; ++x)
            ;
        for (++x; vec[x % 13]; ++x)
            ;
        vec[x % 13] = i + 1;
    }

    for (int i = 0; i < 13; ++i)
        std::cout << vec[i] << " ";
    std::cout << std::endl;
}
