This time, I will show how to maintain an extended suffix array (suffix array, inverse of suffix array, and lcplcp array) while being able to add or remove some character at the beginning of the string in O(logn)O(logn) amortized time. It can be used to overkill solve problem M...
Substring compression problems We initiate a new class of string matching problems called Substring Compression Problems. Given a string S that may be preprocessed, the problem is to quickly find the compressed representation or the compressed size of any query substr... G Cormode,S Muthukrishnan ...
Therefore the suffix array for ss will be (2, 3, 0, 4, 1)(2, 3, 0, 4, 1).As a data structure it is widely used in areas such as data compression, bioinformatics and, in general, in any area that deals with strings and string matching problems....
Suffix array is a very nice array based structure. Basically, it is a lexicographically sorted array of suffixes of a strings. For example, let's consider a strings = abakan. A word abakan has 6 suffixes{abakan , bakan, akan, kan, an, n}and its suffix tree looks like this: ...
linear time suffix array construction algorithmsThe suffix array is a data structure that finds numerous applications in string processing problems for both linguistic texts and biological data. It has been introduced as a memory efficient alternative for suffix trees. The suffix array consists of the...

The suffix automaton itself will be stored in an array of these structures statestate. We store the current size szsz and also the variable lastlast, the state corresponding to the entire string at the moment.const int MAXLEN = 100000; state st[MAXLEN * 2]; int sz, last; ...

We believe that this new idea of using an information theoretic approach to suffix sorting could shed a new light on the problems of suffix array construction, their analysis, and applications. Acknowledgements This work was partially supported by a DOE CAREER grant: No: DE-FG02-02ER25541, ...
Briefly, a suffix array for a text T = t1 ... t n is an array of integers that specifies the lexicographic order of the suffixes of T; each entry of this array is the start position of a suffix of T. This simple data structure is enhanced by pre-calculating other indexing structures...
