postorderTraversal-2 最小值栈 两个队列实现一个栈 表达式求值 五、链表 链表,在节点间穿针引线。 为什么链表很重要? 不同于 动态数组、栈、队列的实现:其底层是依托静态数组,靠 resize 解决固定容量问题, 链表是真正的动态数据结构,也是最简单的动态数据结构。 能够帮助我们更深入地理解引用(指针)与递归。 优...
First, an explicit expression for the inverse of the Haar matrix is presented. Then, using it, we propose a combined preorder and postorder traversal algorithm to solve the generalized Sylvester matrix equation. Finally, the efficiency of the proposed method is discussed by a numerical example....
