        if (-1 == ptr)
            return results.toArray(new String[results.size()]);
    }

    // iteratively (to prevent stack overflow) search each branch of the graph
    Stack<StackEntry> stack = new Stack<StackEntry>(); // a stack of paths to traverse. This prevents the StackOverflowException.

        StackEntry entry = stack.pop();

        // if current node is a valid word
        if (canTerminate(entry.node)) {
            results.add(String.valueOf(entry.chars) + entry.subword);
