是一种数据结构的编程代码，程序实现一种算法，在铁路系统上在两点间得到最短路径-is a data structure of the programming code, procedures to achieve an algorithm, the railway system in the period between 2:00 Shortest Path

这是一个用C++编写的代码,实现了最小堆和最小左偏树在插入删除元素性能方面进行比较. -This is a preparation of the C code, the smallest and youngest sculpture tree in the left side inserted delete elements performance comparisons.

ACM,竞赛题目,我已经在上面测试过了,可以用,题目是ARGUS,希望大家可以喜欢,花了长时间才弄好的-ACM, the title race, I have tested in the above, you can use the title ARGUS, hope everyone can like it, spent a long time before the promotion of

哈夫曼树算法 根据给定的n个权值{w1,w2,……wn}，构造n棵只有根结点的二叉树，令起权值为wj 在森林中选取两棵根结点权值最小的树作左右子树，构造一棵新的二叉树，置新二叉树根结点权值为其左右子树根结点权值之和 在森林中删除这两棵树，同时将新得到的二叉树加入森林中 重复上述两步，直到只含一棵树为止，这棵树即哈夫曼树 -Huffman tree algorithm based on a given n-weights (w1, w2, ... ... wn), construct n trees only a root node of the tree, so that from the right value of wj in the forest root node to select two the right tree for the value of the smallest subtree around, a new binary tree structure, the right to buy a new tree root node value of its subtree root node around the right value in the forest and delete these two trees, At the same time, the new binary tree obtained by adding the forest to repeat the above two steps until a tree containing only the date, that is, Huffman tree tree

利用桶排序给数组a排序，建立的桶为b和e，其中b为含有十万个桶，e为只有一个链表的桶，然后对b和e使用插入算法排序，比较两种算法的时间，b需要40毫秒左右，e需要9到10分钟。-use barrels a ranking to the array, in order to establish the barrels of b and e, b to contain 100,000 barrels of only one e Chain barrels, and then to b e used to insert sorting algorithm, the algorithm for comparing two hours, b needs about 40 milliseconds, e needs 9 10 minutes.

使用odbc实现对excel数据表格的存取，没有压缩密码-using odbc to excel to achieve data access forms, no compression Password

在顺序存储结构上,采用顺序查找算法，直接插入排序算法等算法查找一关键字,输出查找结果-In the sequential storage structure, using the sequential search algorithm, sorting algorithm directly into the search for a keyword such as algorithms, the output search results
