Problems on strings

String-to-string correction problem

In computer science, the string-to-string correction problem refers to determining the minimum cost sequence of edit operations necessary to change one string into another (i.e., computing the shortest edit distance). Each type of edit operation has its own cost value. A single edit operation may be changing a single symbol of the string into another (cost WC), deleting a symbol (cost WD), or inserting a new symbol (cost WI). If all edit operations have the same unit costs (WC = WD = WI = 1) the problem is the same as computing the Levenshtein distance of two strings. Several algorithms exist to provide an efficient way to determine string distance and specify the minimum number of transformation operations required. Such algorithms are particularly useful for delta creation operations where something is stored as a set of differences relative to a base version. This allows several versions of a single object to be stored much more efficiently than storing them separately. This holds true even for single versions of several objects if they do not differ greatly, or anything in between. Notably, such difference algorithms are used in molecular biology to provide some measure of kinship between different kinds of organisms based on the similarities of their macromolecules (such as proteins or DNA).

Java Manipulating Strings

More videos like this online at http://www.theurbanpenguin.com We do quite a lot in this video so if you are new to Java you will get a lot out of this. First we revisit StringBuilder and the reverse method. Then looking at how we can assign non-string values to strings with concatenation

stringr: String Matching

The stringr library is part of the R tidyverse and provides a range of convenience functions for working with character strings. In this lesson, we learn how to use stringr to do pattern matching: detecting whether certain substrings or string patterns (regular expressions) exist in text.
