在市场经济运行中，必须遵循等价交换的原则。对“等价交换”理解正确的是（） A.是指每

With hundreds of millions of electronic（）taking place daily, businesses and organizations have a p incentive to protect the（）of the data exchanged in this manner, and to positively ensure the（）of those involved in the transactions. This has led to an industry-wide quest for better, more secure methods for controlling IT operations, and for deploying p security mechanisms deeply and broadly throughout networked infrastructures and client devices. One of the more successful concepts to engage the imaginations of the security community has been the development of standards-based security（）that can be incorporated in the hardware design of client computers. The principle of encapsulating core security capabilities in（）and integrating security provisions at the deepest levels of the machine operation has significant benefits for both users and those responsible for securing IT operations.

One of the more successful concepts to engage the imaginations of the security community has been the development of standards-based security（）that can be incorporated in the hardware design of client computers.

假设两个队列共享一个循环向量空间(参见右图)，其类型Queue2定义如下：

typedef struct

DateType data[MaxSize];

int front[2] ,rear [2];

Queue2;

对于i=0或1，front[i]和rear[i]分别为第i个队列的头指针和尾指针。函数EnQueue (Queue2*Q，int i，DateType x)的功能是实现第i个队列的入队操作。

[函数3.1]

int EnQueue (Queue2*Q,int i,DateType x)

//若第i个队列不满，则元素x入队列，并返回1; 否则返回0。

if (i＜0 || i＞1) return 0：

if (Q-＞rear [i] ==Q-＞front[ (1) ])

return 0：

Q-＞data[ (2) ]=x;

Q-＞rear[i]=[ (3) ];

return 1：

[函数说明3.2]

函数BTreeEqual(BinTreeNode *T1，BinTreeNode *T2)的功能是用递归法判断两棵二叉树是否相等，若相等则返回1，否则返回0。函数中参数T1和T2分别为指向这两棵二叉树根结点的指针。当两棵树的结构完全相同并且对应结点的值也相同时才被认为相等。

已知二叉树中的结点类型BinTreeNode定义为：

struct BinTreeNode

char data;

BinTreeNode *left, *right;

;

其中data为结点值域，left和right分别为指向左、右子女结点的指针域。

[函数3.2]

int BTreeEqual(BinTreeNode* T1,BinTreeNode* T2)

if (T1==NULL ＆＆ T2==NULL) return 1; //若两棵树均为空则相等

else if( (4) )return 0; //若一棵为空一棵不为空则不等

else if( (5) )return 1; //若根结点值相等并且左、右子树

//也相等则两棵树相等，否则不等

else return 0：
