5.5 (Enhanced Flag Quiz App) Make the following enhancements to the Flag Quiz app:
a) Count the number of questions that were answered correctly on the first try. After all the questions have been answered, display a message describes how well the user performed on first guesses.
b) Keep track of the score as the user proceeds through the app. Give the user the most points for answering correctly on the first guess, fewer points for answering correctly on the next guess, etc.
c) Use a SharedPreferences file to save the top five high scores.
d) Add multiplayer functionality.
e) If the user guesses the correct flag, include a “bonus question” asking the user to name the capital of the country. If the user answers correctly on the first guess, add 10 bonus points to the score; otherwise, simply display the correct answer, then allow the user to proceed to the next flag.
f) After the user answers the question correctly, include a link to the Wikipedia for that country so the user can learn more about the country as they play the game. In this version of the app, you may want to allow the user to decide when to move to the next flag.
