递归是计算机科学中一个非常重要的概念,对于斐波那契那种比较简单的递归,分析起来比较容易,但是由于二叉树涉及指针操作,所以模仿下遍历过程中系统栈的情况. 以二叉树中序遍历为例演示: //二叉树定义 struct TreeNode { TreeNode* left; TreeNode* right; int val; TreeNode(int x) :val(x), left(NULL), right(NULL) {} }; 中序遍历的递归实现: 假设二叉树如图所示: 其中序遍历序列为\(2413\…

-stack           0x00000800-heap            0x00000800 stack - 又称系统栈(system stack),用于: 保存函数调用后的返回地址; 给局部变量分配存储空间; 传递函数参数; 保存临时结果; heap - 编译器提供的运行时支持库的一些函数(如malloc/calloc/realloc),允许运行时为变量动态分配存储器.这些存储器就放置在.system段的全局池(global pool)或堆(heap)中. 这个动态存储池的大小…

今日遇见一个开超市的朋友,真没想到在高校开超市一个月可以达到月净利润50K,相比起我们程序员的工资,真是不可同日而语,这个世道啊,真是做程序员不如经商开超市, 我们高科技的从业者,真是造原子弹不如卖茶叶蛋. 请见代码详细注释 //  修复涉及后视列表的Win2K兼容性 //  Fixes Win2K compatibility regarding lookaside lists. // #ifndef _WIN2K_COMPAT_SLIST_USAGE // Add content(增加内容)…
