还原需要16次，不是20次，源码和输出结果如下：
/****************************
    模拟洗牌-完美洗牌法

void main()
{
int i,j;
int a[52],b[52];
char poker[52][4]={
" AH"," 2H"," 3H"," 4H"," 5H"," 6H"," 7H"," 8H"," 9H","10H"," JH"," QH"," KH",
" AC"," 2C"," 3C"," 4C"," 5C"," 6C"," 7C"," 8C"," 9C","10C"," JC"," QC"," KC",

" AS"," 2S"," 3S"," 4S"," 5S"," 6S"," 7S"," 8S"," 9S","10S"," JS"," QS"," KS"};

for(i=0;i<52;i++) a[i]=i;
for(j=0;j<52;j++)
{
    printf("%s ",poker[a[j]]);
    if(j%13==12) printf("\n");
}
printf("----\n");

for(i=0;i<16;i++)
{
    for(j=0;j<26;j++)
    {
    b[2*j] = a[j];
    }
    for(j=26;j<52;j++)
    {
    b[2*(j-26)+1] = a[j];
    }
    for(j=0;j<52;j++)
    {
        printf("%s ",poker[b[j]]);
        if(j%13==12) printf("\n");
    }
    printf("----\n");

    for(j=0;j<52;j++) a[j]=b[j];
}
getch();
}

输出结果：

A、B、C为数组
---------------------------------
A(16)把第一行和第二行导入

B(16)把第三行和第四行导入

C(32)1：取A（2-16）内数值各位移一位，填入
2：取B（1-15）内数值，填入剩余位置
A的位置+1就行，B的位置*2

然后在把C中1-16导入A，把17-32导入B
-----------------------------------
以上就是完成了一次洗牌，的基本算法了。然后循环

是否经过20次就还原，就不知道了。我没仔细算过。细节部分自己注意吧！
