The program generates a lottery using the random() method (line 6) and prompts the user
to enter a guess (line 11). Note that guess % 10 obtains the last digit from guess and guess
/ 10 obtains the first digit from guess , since guess is a two-digit number (lines 18-19).
The program checks the guess against the lottery number in this order:

1. First, check whether the guess matches the lottery exactly (line 24).

2. If not, check whether the reversal of the guess matches the lottery (lines 26-27).

3. If not, check whether one digit is in the lottery (lines 29-32).

4. If not, nothing matches and display "Sorry, no match" (lines 34-35).
