Q 5. You've saved the password to access your Bitcoins on your personal computer. You have created an application that encrypts the password. To decrypt, you need to perform an operation between two integers, say A and B, as described below. Let X and Y be the numbers obtained by REVERSING A and B. For example, the reverse of 123 is 321 , and the reverse of 320 is 23 (leading zeroes are discarded). If both X and Y are Even, then the answer is X+Y. If EXACTLY ONE of X and Y is Even, then the answer is A+B. Otherwise, the answer is AB
