Thời gian phức tạp. O[log10n]
Không gian phụ trợ. Ô[1]

Cách tiếp cận khác. Vấn đề có thể được giải quyết mà không cần đảo ngược số. Chúng tôi có thể trích xuất tất cả các chữ số từ số một từ cuối. Nếu số ban đầu là số lẻ thì chữ số cuối cùng phải ở vị trí lẻ nếu không nó sẽ ở vị trí chẵn. Sau khi xử lý một chữ số, ta có thể đảo ngược trạng thái từ lẻ sang chẵn và ngược lại

Dưới đây là việc thực hiện các phương pháp trên.
