如何使用Go lang在另一个字符串中插入一个字符串

Question

Most programming languages have a function that allows us to insert one string into another string. For example, I can take the string Green and the string HI, and perform an operation Green.insert(HI,2) to get the resulatant string GrHIeen. But such a function does not come with the standard GO lang library.

Is there any Golang function which I can use to insert a string inside an string?

For example

string = "</table></body></html>"

// I want Following Output

string = "</table><pagebreak /></body></html>"

You can simply use slice operations on the string:

package main

func main() {
    p := "green"
    index := 2
    q := p[:index] + "HI" + p[index:]
    fmt.Println(p, q)
}
