$$ Write a program that reads a string that contains a test taker$$s answers to multiple choice exam questions and grades the test

$$ For example, assume that the correct answers $($for $11$ questions$)$ are defined as:

# Define a string containing the correct answers

CORRECT$\_$ANSWERS $=$adbdcacbdac$$

$$ Then Ask for the User$$s answers $($in a string$)$

$$ And see if each answer is correct or not $($hint: compare each character in the defined string and the string the User inputs$)$

$$ Keep a percent score of correct answers

$$ At the end, Display the Missed questions, and the percent score as shown below:

Enter your exam answers: acddcbcbcac

You missed $4$ questions: aXXdcXcbXac

Your score is: $64$ percent
