- *     <p>(Display leap years) Write a program that displays all the leap years, 10 per line, from
- *     101 to 2100, separated by exactly one space. Also display the number of leap years in this
- *     period.
+ *     <p>(Game: lottery) Revise Listing 3.8, Lottery.java, to generate a lottery of a two-digit
+ *     number. The two digits in the number are distinct. (Hint: Generate the first digit. Use a
+ *     loop to continuously generate the second digit until it is different from the first digit.)
