array[j] = tem;

i++;

j--;

}

return String.valueOf(array);

}

static String reverseSentence(String string){

String reversedString=reverse(string);

String[] splitStrings=reversedString.split(" ");

String resultString="";

for(String str:splitStrings){

resultString=resultString+reverse(str)+" ";

}

return resultString;
