    String outputString = "";
    String aux = "";

    for(int itr=0;itr<inputString.length();itr++){    

        // reverse the words if a whitespace occurs.   
       if(inputString.charAt(itr) == ' '){
          outputString += reverseString(aux) + " ";
          aux = "";
       }
       else{ // extract the word from the string 
          aux += inputString.charAt(itr);
       }
    }
    // reverse the last word of the string
    outputString += reverseString(aux);
    System.out.println(outputString);
  }
  

  public static String reverseString(String str){
    
   String aux = "";
   for(int itr = str.length()-1;itr>=0;itr--){
     aux += str.charAt(itr);
   }
   return aux;
  } 


  public String getStringFromUser(){

     try{
     System.out.println("Enter String to be reversed");
     BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
     return br.readLine();
     }
     catch(Exception e){e.printStackTrace();}
     return "ekansh";
