levenshtein edit distance algorithm

edit Distance definition :The editing distance, also known as the Levenshtein distance , is the minimum number of edit operations required between two strings, from one to another.Licensing edits include replacing one character with another,

Describe:There is many magic numbers whose lengths is less than 10. Given Some queries, each contains a single number, if the Levenshtein distance (see below) between the number in the query And a magic number is no. than a threshold, we call the

Instructions for useLook at the description of the Levenshtein () function in the manual: The Levenshtein () function returns the Levenshtein distance between two strings. Levenshtein distance, also called edit distance, refers to the minimum

Basic introductionLevenshtein distance is a string measure (string metric) that calculates the degree of difference between two strings. We can assume that the Levenshtein distance is the minimum number of times required to edit a single character

The function is mainly used to calculate the number of matching characters for two strings, or to calculate the similarity between the two strings (expressed in percentages ). Compared with the similar_text () function, the levenshtein () function

TurnIt's not difficult to understand, but it's practical.The core formula is the following:(1)1. Introduction of Baidu Encyclopedia:Levenshtein distance, also known as the editing distance, refers to the minimum number of edit operations required

In the verification code to identify the need to compare the similarity of character code to the "editing distance algorithm", about the principle and C # implementation to make a record.According to Baidu Encyclopedia introduction:The editing
