How to reverse a string in Go?

Question

How can we reverse a simple string in Go?

Answer 1

Building on Stephan202's original suggestion, and appears to work for unicode strings:

import "strings";

func Reverse( orig string ) string {
    var c []string = strings.Split( orig, "", 0 );

    for i, j := 0, len(c)-1; i < j; i, j = i+1, j-1 {
        c[i], c[j] = c[j], c[i]
    }

    return strings.Join( c, "" );
}

Alternate, not using strings package, but not 'unicode-safe':

func Reverse( s string ) string {
    b := make([]byte, len(s));
    var j int = len(s) - 1;
    for i := 0; i <= j; i++ {
        b[j-i] = s[i]
    }

    return string ( b );
}
