reverse string slice golang code example

Example 1: reverse a string in golang

func reverse(s string) string {
	runes := []rune(s)
	for i, j := 0, len(runes)-1; i < j; i, j = i+1, j-1 {
		runes[i], runes[j] = runes[j], runes[i]
	}
	return string(runes)
}

Example 2: golang slice string

First of all, you should really read about strings, bytes and runes in Go.

And here is how you can achieve what you want: Go playground (I was not able to properly paste arabic symbols, but if Chinese works, arabic should work too).

    s := "abcdefghijklmnop" 
    fmt.Println(s[2:9]) 

    s = "something which is display"
    fmt.Println(string([]rune(s)[2:9]))
