Ukkonen Suffix Tree Algorithm

In computer science, a suffix tree (also named PAT tree or, in an earlier form, position tree) is a compressed trie containing all the suffixes of the given text as their keys and positions in the text as their values.\displaystyle S } , locating a substring if a certain number of mistakes are allowed, locating matches for a regular expression shape etc. He provided the first online-construction of suffix trees, now known as Ukkonen's algorithm, with working time that matched the then fastest algorithms.anbnanbn$. Weiner's Algorithm c finally uses compressed attempt to achieve linear overall storage size and run time. Farach's algorithm has become the basis for new algorithms for constructing both suffix trees and suffix arrays, for example, in external memory, compressed, succinct, etc.
