Hi
I think we can create a package to reverse a string and can use it whenever
needed.
reverse.go
package strutil
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)}
come to your original .go programm and import that above reverse.go util package
package main
import(
"fmt"
"github.com/himanshu/go_code/strutil" . // Path of reverse.go file
)
func main() {
fmt.println(strutil.Reverse("Hello World"))
}
It dosent take too much memory as well
