Learn the definition, applications and algorithms of the longest common substring problem in computer science. Compare the time and space complexity of suffix tree and dynamic programming methods.
Edit distance is a string metric that measures how dissimilar two strings are by counting the minimum number of operations to transform one into the other. Learn about different types of edit distance, their properties and applications, and how to compute them efficiently.
Learn about the string metric that measures the difference between two sequences by the minimum number of edits. Find definitions, examples, applications, bounds, and algorithms for computing the Levenshtein distance.

Only for strings of the same length. Number of changed characters. " ka rol in" and "ka thr in" is 3. Levenshtein distance and Damerau–Levenshtein distance: Generalization of Hamming distance that allows for different length strings, and (with Damerau) for transpositions kitten and sitting have a distance of 3. kitten → sitten (substitution ...
Learn the definition, properties, and algorithms of the longest common subsequence (LCS) problem, a classic computer science problem with applications in data comparison and bioinformatics. See examples, complexity analysis, and dynamic programming solution for two sequences.
GNU Octave is a free software that helps in solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with MATLAB. It is written in C++ and has a Graphical User Interface (GUI) and an OpenGL-based graphics engine.
A string is a sequence of characters used to store human-readable or machine-readable data in computer programming. Learn about the history, types, length, encoding and operations of strings in different programming languages.
