Write a program that scores a blackjack hand. In blackjack, a player receives from two to five cards. The cards 2 through 10 are scored as 2 through 10 points each. The face cards (jack, queen, and king) are scored as 10 points. The goal is to come as close to a score of 21 as possible without going over 21. Hence, any score over 21 is called "busted". The ace can count as either 1 or 11, whichever is better for the user. The user is asked how many cards they have, and the user responds with an integer 2, 3, 4, or 5. The user is then asked for the card values. Card values are 2 through 10, jack, queen, king, and ace. A good way to handle input is to use the type char. Input the values 2 through 9 as the characters '2' through '9'. Input the values 10, jack, queen, king, and ace as the characters 't', 'q', 'k', and 'a'. Allow upper and lowercase letters. After reading in the values, the program should convert them from character values to numeric card scores, taking special care for aces. The output is either [2.21] or the word busted. Your program should include a loop that lets the user repeat this calculation until the user says they are done. You may have multiple long multiway branches.
