可以看到S.index()与S.find()类似,不过索引字符串中的子串没找到会报错。 而S.find()在找不到substring时,不会报错,而会返回-1 list 和 tuples获取索引: list.index(), tuple.index() ist和tuple有一个索引方法来获取元素的位置 : alist = [10, 16, 26, 5, 2, 19, 105, 26] #返回元素为16的...

spoj 7258 Lexicographical Substring Search (后缀自动机) 题意:给出一个字符串,长度为90000。询问q次,每次回答一个k,求字典序第k小的子串。 解题思路:构造出sam后,类似splay求前驱的做法,不断的逼近答案。我们知道,sam里从s走到某一节点即为一个子串,所以我们在每个节点下记录一个cnt,表示该节点下,能走到的...
