车牌照号码基数排序

[like001]

对车牌照号码进行链式存储，然后对其进行基数排序（例NA3002）并可实现对排序结果的二分查找算法 急求！！！！！！！

这是一个二分查找的例子：

    // 二分法检索hash值
    bool finded = false;
    int left = 0;
    int right = _itemCount - 1;
    int mid = 0;
    static DWORD* hashAddr = _indexBuf + _itemCount;
    while (left <= right)
    {
        mid = (left + right) / 2;
        const DWORD* p = hashAddr + mid;
        if (*p == hash)
        {
            finded = true;
            p -= _itemCount;
            if (HIWORD(*p) > _buf.size()) _buf.resize(HIWORD(*p));
            SetFilePointer(_file, LOWORD(*p), NULL, FILE_BEGIN);
            ReadFile(_file, &_buf[0], HIWORD(*p), &reserve, NULL);
            break;
        }

        if (hash > *p) left = mid + 1;
        else right = mid - 1;
    }
