题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=2647 题目大意:要给n个人发工资,告诉你m个关系,给出m行每行a b,表示b的工资小于a的工资,最低工资为888,求最少要发多少工资,如果关系矛盾就输出“-1”. 解题思路:用拓扑排序解决,但是要分层,类似于多棵树的层次遍历,用dis[i]存储i所在层数(起点为0层),因为要是所有条件都符合,所以dis[i]取最大值.还有注意判断是否存在环. 代码: #include<iostream> #inc…

HDU.2647 Reward(拓扑排序 TopSort) 题意分析 裸的拓扑排序 详解请移步 算法学习 拓扑排序(TopSort) 这道题有一点变化是要求计算最后的金钱数.最少金钱值是888,最少的差额是1,如1号的人比2号钱要多,2号至少是1号人的钱数+1.根据拓扑排序的思想,我们只需要类比二叉树的层序遍历,每次取出入度为0的节点做处理,累加金钱数量,然后再取出入度为0的节点处理.直到取出所有的点或者判断成环即可. 代码总览 #include <iostream> #include <…

Reward HDU - 2647 题意:每个人的起始金额是888,有些人觉得自己做的比另一个人好所以应该多得一些钱,问最少需要花多少钱,如果不能满足所有员工的要求,输出 -1 样例1: 2 1 1 2 输出1777 1认为自己的报酬应该比2多,所以2为888,1为889是最小的情况 样例2: 5 4 1 2 2 5 2 4 4 3 输出4446 相当于给定一张图,n个节点,m条边,问你是否存在环,若存在,则输出-1,为什么?因为存在环的话无法满足所有人的需求例如1->2,1->1,1想比2大…

Problem Description 糟糕的事情发生啦,现在大家都忙着逃命.但是逃命的通道很窄,大家只能排成一行. 现在有n个人,从1标号到n.同时有一些奇怪的约束条件,每个都形如:a必须在b之前.同时,社会是不平等的,这些人有的穷有的富.1号最富,2号第二富,以此类推.有钱人就贿赂负责人,所以他们有一些好处. 负责人现在可以安排大家排队的顺序,由于收了好处,所以他要让1号尽量靠前,如果此时还有多种情况,就再让2号尽量靠前,如果还有多种情况,就让3号尽量靠前,以此类推. 那么你就要安排大家的顺…
