package main

import (
    "fmt"
    "unicode"
)

func moveSpecialCharactersToBeginning(s string) string {
    var specials []rune
    var chars []rune

    for _, ch := range s {
        if unicode.IsLetter(ch) || unicode.IsDigit(ch) || unicode.IsSpace(ch) {
            chars = append(chars, ch)
        } else {
            specials = append(specials, ch)
