给定单词w的后缀集合上的有序字母表和按照词典顺序排列的排列,本文提出了一种线性时空方法来确定单词w‘在其后缀上是否具有相同的排列。使用这种方法,我们还能够构建所有后缀具有相同排列的单词的类,首先是最小的一个。最后,我们注意到,这项工作可以导致一种方法,用于在线性时间内随机生成Lyndon词,或者用于计算长度为n的Lyndon词的集合。
Given an ordered alphabet and a permutation, according to the lexicographic order, on the set of suffixes of a word w , we present in this article a linear time and space method to determine whether a word w' has the same permutation on its suffixes. Using this method, we are then also able to build the class of all the words having the same permutation on their suffixes, first of all the smallest one. Finally, we note that this work can lead to a method for generating a Lyndon word randomly in linear time or for computing the set of Lyndon words of length n .
