 * <p>
 * 1. If the user input matches the lottery number in the exact order, the award
 * is $10,000.
 * <p>
 * 2.If all digits in the user input match all digits in the lottery number, the
 * award is $3,000.
 * <p>
 * 3. If one digit in the user input matches a digit in the lottery number, the
 * award is $1,000
