Write a function game() that teaches children how to add single-digit numbers. The function should take an integer n as a parameter and ask the child to answer n single-digit addition questions. The numbers should be chosen randomly from the range [0, 9] (that is including both 0 and 9). The user will enter the answer when prompted. Your function should print ‘Correct’ for correct answers and ‘Incorrect’ for incorrect answers. After n questions, the function should print the number of questions answered correctly. The function should also recover gracefully from non-integer values typed by the user. In those cases, the function should re-prompt the child to enter the answer without counting the invalid value either as correct or incorrect. The following shows several sample runs of the function:
