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.…

题目大意:就是给定一组字母的大小关系判断他们是否能组成唯一的拓扑序列. 是典型的拓扑排序,但输出格式上确有三种形式: 1.该字母序列有序,并依次输出: 2.判断该序列是否唯一: 3.该序列字母次序之间是否有矛盾,即是否有环存在: 而这三种形式的判断是有顺序的:先判断(3)是否有环,再判断是否有序(1),最后才能判断是否能得出结果(2).注意:对于(2)必须遍历完整个图,而(1)和(3)一旦得出结果,对后面的输入就不用做处理了. #include<cstdio> #include<cstr…
