无环连通图G=(V, E)亦称为自由树T，其直径是树中所有顶点之间最短路径的最大值，设计一个算法求T的直径(Acyclic connected graph G = (V, E) is also known as free tree T, whose diameter is the tree of shortest paths between all vertices maximum design an algorithm for the diameter of T)

包括链表的各项操作，添加、删除、修改等。还包括单项连标和双向链表。(including the operation, add, delete, revise. Also including individual targets and even two-way linked list.)

哈夫曼树，基本的数据结构，用来编码和解码、用数组作为存储结构实现，

航迹起始中的逻辑航迹起始算法源代码，本代码具有很好的航迹起始效果！ (Track initiation logic for track initiation algorithm source code, this code has the effect of track initiation)

C++中，对链表的增删改查的基本使用，值得学习(C++, on the list of CRUD basic use, it is worth learning)

二叉树的链式存储、先序中序遍历和层次遍历。（构造一棵树并输入数据，编写三个函数，非别是树的前序递归遍历算法、树的后序递归遍历算法、树的非递归中序遍历算法（这里的非递归以中序为例）。在主程序中调用这三个函数进行树的遍历，观察用不同的遍历方法输出的数据的顺序和验证递归与非递归输出的数据是否一样。）(Chain store binary tree, preorder traversal and hierarchy traversal.)

编程实现Prim算法，基于最小堆数据结构，生成最小代价生成树。 （其中随机生成点和边，形成连通图） 根据输入的顶点数的不同，分析时间复杂度。(Implement Prim’s algorithms based on min-heap and disjoint set data structure for constructing a minimum cost spanning tree. Generate weighted undirected complete graph for given size n according to the following approach: 1) Randomly generate n points ( ) on a plane 2) Randomly generate k pairs of points as edges of the graph. 3) The weight of an edge of the graph is defined as the the Euclidean distance between two endpoints of the edge. )

归并排序,复习排序算法，在不同环境下，寻找时间复杂度最少的排序算法( Merge sort, review sorting algorithm, in different contexts, looking for the least time complexity of sorting algorithm)

说明：  由数字1和0组成迷宫，0代表可走路径，程序会用坐标的形式给出每一步的走法(Composed by a maze of numbers 1 and 0, 0 to go the path, the program will use the coordinates given in the form of moves at each step)

实现对二叉树的操作：建树、遍历、求层高、叶子数和结点数等(binary tree)
