QUESTION

Shortest not repeatable Substring with Suffix-Tree

Asked 2021-May-04 at 22:31

I need to design an efficient algorithm that finds the Shortest non-repeatable Substring in a text. In essence; the shortest string that appears only once in a text. This has to be made only with suffix-tree

Example 1:

Text: AATGCCTA then Result: G

Example 2:

Text: AAAAGGGG then Result: AG

The shortes non-repeatable substring is the shortest unique prefix of all the suffixes.

QUESTION

Implementing pattern matching in a trie tree

Asked 2020-Apr-22 at 19:02

I am currently using a trie implementation from this stack overflow post:

Getting a list of words from a Trie

to return a list of words which match a given prefix. I'm then using regex to filter out the words which don't meet the entire specified pattern.

EX: if the pattern I'm searching for is: CH??S? and this is a subset of the dictionary which matches my initial prefix: {CHABAD, CHACHA, CHARIOT, CHATTED, CHEATER, CHOMSKY, CHANNEL CHAFED, CHAFER, CHAINS, CHAIRS, CHEESE, CHEESY CHRONO, CHUTES, CHISEL}

I would search the trie with 'CH' prefix and then filter out words which match my desired pattern of CH??S? (CHEESY, CHEESE, CHISEL) and return those.

I am wondering if there is a faster way to do this to avoid using the regex in the final step. I thought I could use a suffix tree (Ukkonen's suffix tree algorithm in plain English )or the boyer-moore algorithm but neither work because they search on suffixes not on patterns.

Here's a nice recursive algorithm you can use that eliminates the need to use a final regex pass. It works by matching a pattern P against a tree T:

It seems to me the problem is that the library is for Clojure on the JVM only, and you are trying to use it on a ClojureScript project.

No such namespace: opennlp.nlp, could not locate opennlp/nlp.cljs, opennlp/nlp.cljc, or JavaScript source providing "opennlp.nlp"

The compiler tried to look for ClojureScript code (extension .cljs) or compatible with both Clojure and ClojureScript (extension .cljc) or plain JavaScript, but found none.

How to create a fast autocomplete feature on the back-end

Asked 2019-Mar-03 at 12:30

I'm quite new to data structures but I was trying to implement an efficient city lookup / city autocomplete feature on the back-end of my application (A nodeJS express server).

Originally I was only loading in memory an array of cities (which was around 20.000 cities); I'd let my client app search a city through the endpoint /search and return them a list of cities that matched what the user was searching:
