Levenshtein

• 说明：​Levenshtein​计算两个字符串之间的​Levenshtein​距离。
• 格式：

Levenshtein(str1, str2 string, costIns, costRep, costDel int) int

• 示例：

func ExampleLevenshtein() {
	var (
		str1    = "Hello World"
		str2    = "hallo World"
		costIns = 1
		costRep = 1
		costDel = 1
		result  = gstr.Levenshtein(str1, str2, costIns, costRep, costDel)
	)
	fmt.Println(result)

	// Output:
	// 2
}

SimilarText

• 说明：​SimilarText​计算两个字符串之间的相似度。  
• 格式：

SimilarText(first, second string, percent *float64) int

• 示例：

func ExampleSimilarText() {
	var (
		first   = `AaBbCcDd`
		second  = `ad`
		percent = 0.80
		result  = gstr.SimilarText(first, second, &percent)
	)
	fmt.Println(result)

	// Output:
	// 2
}

Soundex

• 说明：​Soundex​用于计算字符串的​Soundex​键。  
• 格式：

Soundex(str string) string

• 示例：

func ExampleSoundex() {
	var (
		str1    = `Hello`
		str2    = `Hallo`
		result1 = gstr.Soundex(str1)
		result2 = gstr.Soundex(str2)
	)
	fmt.Println(result1, result2)

	// Output:
	// H400 H400
}
