String[] temp;
temp = input.split(" ");
System.out.println("Array length : " + temp.length);
for (int i = temp.length; i > 0; i--)
System.out.print(temp[i-1] + " " );
System.out.println("");
}

public static String reverseSentence(String a){
    StringBuilder result = new StringBuilder();
    Stack stack = new Stack();
    String[] temp;
    temp = a.split(" ");
    for (String s : temp){
        stack.push(s);
    }
    while(!stack.empty()){
        result.append(stack.pop() + " ");
    }
    return result.toString();
    }

=0; $index--)
		{
			$result[strlen($word)-1 - $index] = $word[$index];
		}
		return implode("", $result);
	}
	// O(n/2) times = O(n) times
	function reverse2($word)
	{
		$temp = "";
		if(strlen($word)%2 == 1)
			$stop = strlen($word)/2;
		else
			$stop = strlen($word)/2-1;
		for ($index = 0; $index
