题意:给出n个字符,m对关系,让你输出三种情况:     1.若到第k行时,能判断出唯一的拓扑序列,则输出:         Sorted sequence determined after k relations: 序列     2.若到第k行,出现环,则输出:         Inconsistency found after k relations.     3.若直到m行后,仍判断不出唯一的拓扑序列,则输出:         Sorted sequence cannot be deter…

https://vjudge.net/problem/POJ-1094 题意 对于N个大写字母,给定它们的一些关系,要求判断出经过多少个关系之后可以确定它们的排序或者排序存在冲突,或者所有的偏序关系用上之后依旧无法确定唯一的排序. 分析 拓扑排序模板题.唯一麻烦点的是判断在第几个式子就可以确定关系.由于在题目中,每个元素的关系都是严格定义的,那么当队列中存在不止一个入度为0的顶点时,可以认为未能成功排序,即还需要更多条件.当拓扑排序算法进行完后,拓扑序列的个数不够,则认为排序出现了矛盾. #in…

Description An ascending sorted sequence of distinct values is one in which some form of a less-than operator is used to order the elements from smallest to largest. For example, the sorted sequence A, B, C, D implies that A < B, B < C and C < D.…
