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

Title, the more detailed the better. Thanks, man. levenshtein("Hello World","ello World"); It only takes 1 steps to add an ' H ' to the second argument! And of course return ' 1 '!This function is quite simple, but: levenshtein("Hello World","ello

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

For example, the more detailed the question, the better. Thank you! {Code...}. It only requires adding & #039; H & #039; in the second parameter. Only one step is required! Of course, Return & #039; 1 & #039! This function is quite simple, but:
