摘要

给定一个整数字母表上的字符串,我们给出了一个算法,该算法在与字符串长度线性的时间内计算属于该字符串的所有不同平方的集合。作为一个应用,我们展示了如何在线性时间内计算最小增广后缀树的树拓扑。除此之外,我们还详细阐述了一种算法,该算法使用压缩的工作空间以简洁的表示计算最长的前表。

Computing All Distinct Squares in Linear Time for Integer Alphabets
Given a string on an integer alphabet, we present an algorithm that computes the set of all distinct squares belonging to this string in time linear to the string length. As an application, we show how to compute the tree topology of the minimal augmented suffix tree in linear time. Asides from that, we elaborate an algorithm computing the longest previous table in a succinct representation using compressed working space.
