6. str = “have a nice day”.split()
   new_str = “”
   for word in str:

7. $str = explode(” “,”have a nice day”);
   $array_rev = array_reverse($str);
   echo implode(” “,$array_rev);

8. str=’Have a nice day’
   new_str=str.split(‘ ‘);
   final_str=[]
   for(let i = new_str.length-1;i>=0; i–){
   final_str.push(new_str[i])
   // console.log(i );
   }
   console.log(final_str.join(‘ ‘));
