Commonly used strings functions in Golang

##6 . 7 . 8. 9. #10. Returns the first occurrence of the substring in the string The index value, if not returned -1 strings.Index("NLT_abc", "abc") // 4Return the index of the last occurrence of the substring in the string, if not return -1 strings.LastIndex("go golang", "go")Replace the specified substring with another substring strings.Replace("go go hello", "go", "go language", n), n can specify you I hope to replace a few, if n=-1 means replace all

Function	Introduction
len(str)	1. Statistics on string length, by bytes len(str)
	2. String traversal, processing Chinese r:=[]rune(str)
	3. Convert string to integer n, err := strconv.Atoi("12")
	4. Integer to string str = strconv.Itoa(12345)
	5. String to []byte var bytes = []byte("hello go")
	[]byte to string str = string([]byte{97, 98, 99})
	10 base to 2, 8, 16 base: str = strconv.FormatInt(123, 2) // 2-> 8, 16
	Find whether the substring is in the specified string strings.Contains("seafood", "foo") //true
	Count how many specified substrings a string has strings.Count("ceheese", "e") //4
	Case-insensitive string comparison (== is case-sensitive) fmt.Println(strings.EqualFold(" abc", "Abc")) // true
##11.
12.
13.
##14. According to a specified character, it is Split identifier, split a string into a string array strings.Split("hello,wrold,ok", ",")
15. Convert the letters of the string to upper and lower case: strings.ToLower("Go") // go strings.ToUpper("Go") // GO
16. Remove the spaces on the left and right sides of the string: strings.TrimSpace(" tn a lone gopher ntrn ")
17. Remove the specified characters on the left and right sides of the string: strings.Trim("! hello! ", " !")
18. Remove the specified characters on the left side of the string: strings.TrimLeft("! hello! ", " !")
19. Remove the specified characters on the right side of the string: strings.TrimRight("! hello! ", " !")
20. Determine whether the string begins with the specified string: strings.HasPrefix("ftp://192.168.10.1 ", "ftp")
21. Determine whether the string ends with the specified string: strings.HasSuffix( "NLT_abc.jpg", "abc") //false
