fifo和lru页面置换算法-fifo and LRU algorithm replacement pages

运用C语言实现寻找输入的“迷宫”矩阵中的可选路径，并将找到的最短路径显示出来。-use C language to find that the "maze" matrix optional path and find the shortest path displayed.

实现已下功能： 1.创建有头结点的单链表存储多项式的指数和系数。 2.输出多项式。 3.多项式的相加。 4.多项式的相乘。

这是我学习数据结构与算法的时候编的双向链表的操作，对学习数据结构与算法的朋友有帮助-This my learning algorithm and data structure of the time series of the two-way linked list, the operation of the learning algorithm and data structure of friends to help! !

一个矩阵类 实现了矩阵的多种运算 希望对大家有帮助-A matrix class implements a variety of matrix operations we want to help

给定n 个整数a ,a , ,an 1 2  组成的序列， a n i | |£ ，1 £ i £ n。如果对于i £ j ，有 0 = å = j k i k a ，则称序列区间i i j a , a , , a +1  为一个零和区间，相应的区间长度为j-i+1。-given n integers a, a, and an 1 2

求解网络中的最短路径。假设某个计算机网络有n个站点，依次编号为1,2,…,n；有的站点之间有直接的线路连接（即这两个站点之间没有其它站点），有的站点之间没有直接的线路连接。如果用三元组（i,j,f）来表示该网络中的站点I和站点j之间有直接的线路连接且它们之间的距离为f 当已知该网络各站点之间的直接连接情况由m个三元组（i1,j1,f1）,(i2,j2,f2),…,(im,jm,fm)确定时，要求计算出对于网络中任意一个站点g(1≤g≤n)到其余各站点的最短距离。-the shortest path. Assuming a computer network n site, followed by No. 1, 2, ..., n; Some sites have direct connections (that is, between two sites are no other site), and some sites have no direct connections. If three yuan (i, j, f) to the network said the site j site and I have direct connections between them but the distance of f the network known as the site of the direct link between the situation by 3 m (i1, j1, f1), ( i2, j2, f2), ..., (im, jm, fm) to determine, calculate requirements for a network site arbitrary g (1 g n) of the rest of the site is the shortest distance.
