题目描述 一个无环的有向图称为无环图(Directed Acyclic Graph),简称DAG图.     AOE(Activity On Edge)网:顾名思义,用边表示活动的网,当然它也是DAG.与AOV不同,活动都表示在了边上,如下图所示:                                         如上所示,共有11项活动(11条边),9个事件(9个顶点).整个工程只有一个开始点和一个完成点.即只有一个入度为零的点(源点)和只有一个出度为零的点(汇点).    关键

题意: 给你两个空瓶子,只有三种操作 一.把一个瓶子灌满 二.把一个瓶子清空 三.把一个瓶子里面的水灌到另一个瓶子里面去(倒满之后要是还存在水那就依然在那个瓶子里面,或者被灌的瓶子有可能没满) 思路:BFS,打印路径时需技巧. //G++ 840K 0MS #include <iostream> #include <cstdio> #include <cstring> #include <cstdlib> #include <stack> #in

链接:UVa 103 题意:给n维图形,它们的边长是{d1,d2,d3...dn},  对于两个n维图形,求满足当中一个的全部边长 依照随意顺序都一一相应小于还有一个的边长,这种最长序列的个数,而且打印随意一个最长子串的路径, 比如:a(9,5,7,3),b(6,10,8,2),c(9,7,5,1),a和b不满足,但c和b满足 分析:首先对没组边长从小到大排序,再对各组图形按最小边排序,再求最大子串, 对于打印路径,能够逆序循环,也可递归求解 #include<cstdio> #include

早晨碰到了一题挺裸的最短路问题需要打印路径:vijos1635 1.首先说说spfa的方法: 其实自己之前打的最多的spfa是在网格上的那种,也就是二维的 一维的需要邻接表+queue 以及对于queue的操作,自己也是醉了 这里贴一个模板(不含打印路径): #include<cstdio> #include<cstring> #include<queue> #include<iostream> using namespace std; const int

给出两个字符串A B,求A与B的最长公共子序列(子序列不要求是连续的).   比如两个串为:   abcicba abdkscab   ab是两个串的子序列,abc也是,abca也是,其中abca是这两个字符串最长的子序列. Input 第1行:字符串A 第2行:字符串B (A,B的长度 <= 1000) Output 输出最长的子序列,如果有多个,随意输出1个. Input示例 abcicba abdkscab Output示例 abca #include <bits/stdc++.h>

题目链接(貌似未报名的不能进去):https://www.nowcoder.com/acm/contest/141/A 题目: 题意:背包题意,并打印路径. 思路:正常背包思路,不过五维的dp很容易爆内存,比赛时无限爆,后面队友提醒用short就过了.不过也可以用滚动减少内存消耗,两种代码实现都贴一下吧~ 五维代码实现如下: #include <set> #include <map> #include <queue> #include <stack> #in

uva 紫书例题,这个区间dp最容易错的应该是(S)这种匹配情况,如果不是题目中给了提示我就忽略了,只想着左右分割忘记了这种特殊的例子. dp[i][j]=MIN{dp[i+1][j-1] | if(match(i,j) , dp[i][k]+dp[k+1][j] | i<=k<=j .}注意初始化dp[i][i]=1,表示1个字符最少需要一个才能匹配,dp[i+1][i]=0,因为可能只有两个字符使得i+1>j-1,我们可以认为中间是空字符已经匹配了. 打印路径利用了递归,很巧妙,lr

624 - CD 题意:一段n分钟的路程,磁带里有m首歌,每首歌有一个时间,求最多能听多少分钟的歌,并求出是拿几首歌. 思路:如果是求时常,直接用01背包即可,但设计到打印路径这里就用一个二维数组标记一下即可. const int N=1e3+10; int n,m,a[N],d[N],v[N][N]; int main() { while(~scanf("%d%d",&n,&m)) { memset(v,0,sizeof(v)); memset(d,0,sizeof(
