@neetcode-gh updated the way stack was iterated using shorter and much concise syntax for this problem, using the java's enhanced for loop

Hi, thank you for the contribution! Agree that the code you provided is better. Since String is immutable, adding would re-create the string every time which is inefficient. StringBuilder makes much more sense.
