说明：  四路归并排序，将原有的二路归并排序改编的四路归并排序(The four-way merge sort to the original way merge sort adaptation of the four-way merge sort)

说明：  用链表的方式实现多项式的加减，其中结构体包含幂次和系数。(Polynomial addition and subtraction with a list of ways in which the structure and contains the power of coefficients.)

用c/c++写的二叉排序树的插入与删除，有兴趣的朋友可以看一下(Insertions and deletions using c/c++ to write binary sort tree)

X位赋0mintest是实现芯片功耗测试不确定位填充算法(X-bit chip is to achieve the power conferred 0mintest test uncertain bit stuffing algorithm)

迷宫求解一般采用“穷举法”，逐一沿顺时针方向查找相邻块（一共四块－东(右)、南(下)，西(左)、北(上)）是否可通，即该相邻块既是通道块，且不在当前路径上。用一个栈来记录已走过的路径栈是限定仅在表尾(top)进行插入或删除操作的线性表。(Maze solving generally use the " exhaustive" one by one to find adjacent blocks in a clockwise direction (a total of four- East (right), South (down), West (left), North (on)) whether to pass, that the both channel blocks adjacent blocks, and not in the current path. Use a stack to record the path traversed stack is limited only in the tail (top) to insert or delete a linear form.)

先序创建二叉树，将二叉树所有节点的左右子树交换，再先序遍历输出(create a binary tree in first order, exchange all the nodes of the binary subtree , then preorder output)

图中计算最短路径，必须覆盖所有的节点，效率很高(to compute the shortest path in the graph)

使用不同的方法解决背包问题：本算法采用的是动态规划方法，比较好的解决背包问题。(Use different methods to solve knapsack problem: The algorithm is a dynamic programming approach, a better solution to knapsack problem.)

8_queen问题的一个自创的算法，还不错！(8_queen)

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.)
