Udi Manber & Gene Myers使用倍增算法(Doubling Algorithm)快速构造后缀数组,其利用了后缀子串之间的联系可将时间复杂度降至O(MlogN),M为模式串的长度,N为目标串的长度;另外基数 排序算法的时间复杂度为O(N);Difference Cover mod 3(DC3)算法(Linear Work Suffix Array Construction)可在O(3N...
So the main task is to build this array lcp . We will use Kasai's algorithm, which can compute this array in O(n) time.Let's look at two adjacent suffixes in the sorted order (order of the suffix array). Let their starting positions be i and ...
使用常见的排序算法结合strcmp函数构建后缀数组,但strcmp为线性时间复杂度,所以不能体现后缀数组的时间优势;1989,Udi Manber & Gene Myers使用倍增算法(Doubling Algorithm)快速构造后缀数组,其利用了后缀子串之间的联系可将时间复杂度降至O(MlogN),M为模式串的长度,N为目标串的长度;另外基数排序算法的时间复杂度...

后缀数组(suffix array)详解 简介:写在前面 在字符串处理当中,后缀树和后缀数组都是非常有力的工具。 其中后缀树大家了解得比较多,关于后缀数组则很少见于国内的资料。 其实后缀数组是后缀树的一个非常精巧的替代品,它比后缀树容易编程实现, 能够实现后缀树的很多功能而时间复杂度也不太逊色,并且,它比后缀树所占用...

For example: Suffix Array of "banana" would look like this: 5→ a3→ ana1→ anana0→ banana4→ na2→ nanaOne naive way to make the suffix array would be to store all suffixes in an array and sort them. If we use an O(Nlog(N)) comparison based sorting algorithm, then the total...
