带参数的宏:  a 和 b 较大值调用f#define CALL_WITH_MAX(a, b)  f( (a) > (b) ? (a) : (b) )当你写出这种宏时,必须为宏中的所有实参加上小括号，否则引起不必要的麻烦看下面不堪思议的事情int a = 5;int b = 0;CALL_WITH_MAX(++a, b) ; //a被累加了两次#de

输入两棵二叉树A和B，判断B是不是A的子结构struct BinaryTreeNode{ double m_dbValue; BinaryTreeNode* m_pLeft; BinaryTreeNode* m_pRight;};bool DoesTree1HaveTree2(BinaryTreeNode* pR

题目：请完成一个函数，输入一个二叉树，该函数输出它的镜像。void MirrorRecursively(BinaryTreeNode *pNode){ if((pNode == nullptr) || (pNode->m_pLeft == nullptr && pNode->m_pRight)) return; BinaryTreeNode *pTemp = pNod
