Example :

func main() {    str := "Hello World"    fmt.Println(strings.LastIndex(str, "l"))}

Program Output 9

func main() {    str := "Hello "    fmt.Println(strings.Repeat(str, 5))}

Program output Hello hello hello hello hello

function : Replace (S, old, new string, n int) string

func main() {    str := "one,two,three"    for _, v := range strings.Split(str, ",") {        fmt.Println(v)    }}

Program output One, one, three

function : Splitafter (S, Sep string) []string
Description : Splits a string in string s into several string slices with character Sep as a delimiter and preserves the delimiter in the original string and returns a string slice
Example :

func main() {    str := "one,two,three"    for _, v := range strings.SplitAfter(str, ",") {        fmt.Println(v)    }}
