In computer science, a suffix array is a sorted array of all suffixes of a string. It is a data structure used in, among others, full-text indices, data-compression algorithms, and the field of bibliometrics. Suffix arrays were introduced by Manber & Myers (1990) as a simple, space efficient alternative to suffix trees. They had … See more Suffix arrays are closely related to suffix trees: • Suffix arrays can be constructed by performing a depth-first traversal of a suffix tree. The suffix array corresponds to the leaf-labels given in … See more The concept of a suffix array can be extended to more than one string. This is called a generalized suffix array (or GSA), a suffix array that contains all suffixes for a set of strings (for … See more Suffix trees are powerful data structures that have wide application in areas of pattern and string matching, indexing and textual statistics. … See more The child table cldtab is composed of three n arrays, up, down and nextlIndex. The information about the edges of the corresponding suffix tree is stored and maintained by the up and down arrays. The nextlIndex array stores the links in the linked list used for … See more A suffix tree can be built in $${\displaystyle {\mathcal {O}}(n)}$$ and can be converted into a suffix array by traversing the tree depth-first also in $${\displaystyle {\mathcal {O}}(n)}$$, … See more The suffix array of a string can be used as an index to quickly locate every occurrence of a substring pattern $${\displaystyle P}$$ within … See more For a suffix array of S, the lcp-interval associated with the corresponding node of suffix tree of S can be defined as: Interval [i,..j], 0 ≤ i ≤ j ≤ n is an lcp-interval of lcp-value, if See more WebSmallest lexicographical rotation of a string using suffix arrays in O (n) Consider a string of length n (1 <= n <= 100000). Determine its minimum lexicographic rotation. For example, …

In this lecture we consider specialized sorting algorithms for strings and related objects. We begin with a subroutine to sort integers in a small range. We then consider two classic radix sorting algorithms—LSD and MSD radix sorts. Next, we consider an especially efficient variant, which is a hybrid of MSD radix ...
