WebConstruct the generalized suffix array along with LCP array (or construct the LCP array later from the suffix array). Add a single zero element as a prefix of the LCP array; add another zero element as a suffix. Find a pair of minimal LCP entries in such a way that there are suffixes of only one string delimited by these entries. WebThe figure on the right is the suffix tree for the strings "ABAB", "BABA" and "ABBA", padded with unique string terminators, to become "ABAB$0", "BABA$1" and "ABBA$2". The …
In computer science, a generalized suffix array (or GSA) is a suffix array containing all suffixes for a set of strings. Given the set of strings $${\displaystyle S=S_{1},S_{2},S_{3},...,S_{k}}$$ of total length $${\displaystyle n}$$, it is a lexicographically sorted array of all suffixes of each string in See more The functionality of a generalized suffix array is as follows: • For a collection or set of strings, $${\displaystyle S=S_{1},S_{2},S_{3},...,S_{k}}$$. • It is a lexicographically … See more • A generalized suffix array can be utilized to compute the longest common subsequence of all the strings in a set or collection.
