二叉树的建立 建立二叉树的过程是一个“插入”过程,下面我们用 个例子来讲解这一过程。 我们想建立这样一棵二叉树,树中的每一个结点有 个整数数据名为data,有两个指针:左指针L,右指 针R,分别指向这个结点的左子树和右子树,显然可 以用如下名为TREE的结构来描述这种结点:

第一章绪论 1、酶的基本概念 酶的概念:具有生物催化功能的生物大分子,按照其化学组成,可以分为蛋白类酶(P 酶)和核酸类酶(R酶)两大类别。 酶工程:酶的生产与应用的技术过程 酶工程的主要內容包括:微生物细胞发酵产酶,动植物细胞培养产酶,酶的提取与分

Quicksort Proposed by C. A.R. Hoare in 1962 Divide-and-conquer algorithm Sorts“ in place”( like insertion sort, but not like merge sort Very practical(with tuning)

Ch. 20 Processes with Deterministic Trends 1 Traditional Asymptotic Results of OlS Suppose a linear regression model with stochastic regressor given by Y=x!3+e,t=1,2,…,T,;B∈R or in matrix form y=xB+E We are interested in the asymptotic properties such as consistency and limiting
