Title: Greatest common divisor of A and BAnalysis: First we need to know what greatest common divisor is, which means that two or more integers have the largest number in total. Well, know what greatest common divisor is, you can solve it, then it is equivalent to compare the number of the approximate, take its equal to the largest one on the right, right? What is the approximate??? An approximate number is one that divides a or b evenly.All right, let's take a look at the code.Code:1#include 2

Levenshtein distance Algorithm: calculate the difference between two strings

Levenshtein distance (LD)-Two string similarity calculation algorithms There are many ways to calculate the similarity between the two strings. Now we can summarize the similarity calculation based on the linear distance algorithm. Levenshtein Distance (LD): LD may measure the similarity between two strings. Their distance is the addition, deletion, and modification of values during the conversion of a string into that string. Example: If str1 = "test", str2 = "test", then LD (str1, str2) =
