sztringösszehasonlítások

The term "sztringösszehasonlítás" is a Hungarian word that translates directly to "string comparison" in English. It refers to the computational process of determining the relationship between two sequences of characters, known as strings. This comparison can take several forms, with the most common being checking for equality, where the algorithm determines if two strings are identical character by character.

Beyond simple equality checks, string comparison encompasses algorithms that quantify the difference between two strings. This is often measured by a "distance" or "edit distance," representing the minimum number of single-character edits (insertions, deletions, or substitutions) required to change one string into the other. Algorithms like the Levenshtein distance are widely used for this purpose, finding applications in spell checking, DNA sequencing, and plagiarism detection.

Another aspect of string comparison involves lexicographical ordering, where strings are compared based on their position in a dictionary. This is fundamental to sorting algorithms and searching databases. Various string comparison techniques are essential in computer science, underpinning many software functionalities and data processing tasks.
