Like this-Using go lang in go lang using (for loop and range fun)

Given a String S, reverse the string without reversing its individual words. Words are separated by dots.

Input : i.like.this.program.very.much Output: much.very.program.this.like.i

package main 
    import (
       "fmt"
       "strings"
    ) 
    func main() {
       str := " i.like.this.program.very.much"
       words := strings.Split(str, " ")
       len := len(words)
       for i := 0; i<len/2; i   {
          tmp := words[len-i-1]
          words[len-i-1] = words[i]
          words[i] = tmp
       }
       str = strings.Join(words," ")
       fmt.Println(str)
    }

package main

import (
    "fmt"
    "strings"
)

func main() {
    s := "i.like.this.program.very.much"
    r := reverseWords(s)
    fmt.Println(s)
    fmt.Println(r)
}

func reverseWords(s string) string {
    words := strings.Split(s, ".")
    reversedWords := reverse(words)
    r := strings.Join(reversedWords, ".")
    return r
}

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