关于啊哈算法——纸牌游戏疑惑

Question

阅读了啊哈算法中纸牌游戏部分，于是打算用c++实现，自己实现的感觉没问题，运行结果不同，各位帮忙看下问题所在。

#include <queue>
#include <stack>
#include <iostream>
#include <array>

using namespace std;

typedef queue<int> queInt;
typedef stack<int> staInt;
void CardGame(queInt& opposedA,queInt& opposedB)
{
    staInt sta;
    array<int,10> arr = { 0 };

    while (!opposedA.empty() && !opposedB.empty())
    {
        // A play a hand
        int iTem = opposedA.front();
        if (arr[iTem])
        {
            int ic = opposedA.front();
            opposedA.pop();
            opposedA.push(ic);
            for (int i = 0; i < sta.size();i++)
            {
                if (sta.top() == iTem)
