数据结构中基于约瑟夫环问题，用C++方式实现的。。。。。(Data structure based on Josephus problem with C++ a manner. . . . .)

POJ 字符串的插入 可以将一定长度的字符串插入之前给出的字符串之中(POJ string can be inserted into a length of string into a string before being given)

实现回溯算法，能解决八皇后问题等～～算法结果优化，时间复杂度较小(Implement backtracking algorithms can solve the eight queens problem, etc. ~ ~)

说明：  由C程序实现的 数学上 滑雪问题 的代码实现，供大家学习用(Ski problem code for all to learn to use)

该代码实现了深拷贝的问题，对于深拷贝进行了一系列的介绍，并且显示其与浅拷贝的区别。(A deep copy of the code issues a series of deep copy for presentation, and shows the difference between a shallow copy.)

　广度优先搜索及深度优先搜索，用C语言实现，比较使用(Breadth-first search and depth first search, using C language, compared with)

说明：  贪心方法是一种改进了的分级处理方法。它首先根据题意，选取一种量度标准。然后按这种量度标准对这n个输入排序，并按排序一次输入一个量。如果这个输入和当前已构成在这种量度意义下的部分最优解加在一起不能产生一个可行解，则不把此解输入加到这部分解中。这种能够得到某种度量意义下的最优解的分级处理方法称为贪心方法。(greedy method is an improvement of the classification methods. According to its first title Italy, and a selection of standards of measurement. Then, under such a standard measure of this sort n input, with an input an order volume. If the input current and constitutes a measure of significance in this part of the optimal solution together not produce a feasible solution. this solution will not put this added to the importation of decomposition. This can be a meaningful measure of the optimal solution hierarchical method, known as greedy method.)

已知线性表中的元素以值递增有序排列，并以单链表作存储结构。试写一高效的算法，删除表中所有值大于mink且小于maxk的元素（若表中存在这样的元素）同时释放被删结点空间，并分析你的算法的时间复杂度（注意：mink和maxk是给定的两个参变量，它们的值可以和表中的元素相同，也可以不同）。(Known linear elements in the table to the value increments ordered, and a single list for the storage structure. Try to write a highly efficient algorithm to delete all values ​ ​ greater than mink and maxk elements smaller than (if there is such an element in the table) while the release of the deleted node space, and analyze your time complexity of the algorithm (Note: mink and maxk is given two parameters variables, their values ​ ​ and elements in the table can be the same or different).)

数据结构的稀疏矩阵的几部分操作，广工的课程设计(Sparse matrix operations)

建立试题库文件，随机产生n个题目； 题目涉及加减乘除，带括弧的混合运算； 利用栈求解表达式的值； 随时可以退出； 保留历史分数，能回顾历史，给出与历史分数比较后的评价( The establishment of test database file, the subject of n randomly generated topics related to addition, subtraction, mixed operations with parentheses use the value of the expression stack solution ready to quit to preserve the historical scores, can look back at history, and history gives the comparison of scores Evaluation 保留历史分数，能回顾历史，给出与历史分数比较后的评价)
