This exercise works very similarly to

**an earlier one** you'd posted, for which you'd received the complete worked solution. Since you still need complete step-by-step help, this would suggest that (1) giving out the answers when no work is shown might not be very helpful for learning, and (2) you need lessons, so that you can understand what you've been shown.

Since we cannot reasonably provide you with lessons within this environment, please study some lessons online:

Once you have studied some lessons (at least two!) and have learned the basic terms and techniques, please attempt the exercise. If you get stuck, please reply showing all of your work and reasoning.

Thank you!
