Use the function design recipe to develop a function named blackjack. This function takes two positive integer values, a and b. The function returns whichever value is closest to 21 without being over 21. It returns 0 if both values are over 21. Some examples: If the values of a and b are 19 and 20, the function returns 20. If the values of a and b are 15 and 21, the function returns 21. If the values of a and b are 17 and 22, the function returns 17. If the values of a and b are 24 and 22, the function returns 0. You are permitted to use local variables, although they aren't necessary. A function that uses ● 3

Use the function design recipe to develop a function named blackjack. This function takes two positive integer values, a and b. The function returns whichever value is closest to 21 without being over 21. It returns 0 if both values are over 21. Some examples: If the values of a and b are 19 and 20, the function returns 20. If the values of a and b are 15 and 21, the function returns 21. If the values of a and b are 17 and 22, the function returns 17. If the values of a and b are 24 and 22, the function returns 0. You are permitted to use local variables, although they aren't necessary. A function that uses 3 Boolean operators will be shorter than one that does not. Your function definition must have type annotations and a complete docstring. Use the Python shell to test blackjack.
