This weird BigDecimal
Fix the bug causing a calculation error in the getValue() method. Don't change method signature. Don't use rounding. Read the supplementary article about the special features of autoboxing.

Caching
In CacheComputeManager, implement the logic of the empty method. Guess what it should do based on the method name and the class's logic.

The archaic word "biathlon"
Amigo, can you believe it? In the 21st century, there was a sport called biathlon. It involved people skiing and shooting targets at special ranges. They had to hit 5 targets in one round of shooting. Participants shot while standing and in a prone position, but we won't go into the details.

And more refactoring
An integer from 0 to 999, inclusive, is randomly chosen. The user enters a number from the keyboard. The program responds, telling the user whether the entered number is more or less than the secret number. If the user guesses the number in 10 attempts, then the program displays: "You guessed it!"

Refactoring the Chain of Responsibility pattern
We have a program that has a logging system that works as follows: if the event's log level is FATAL, the manager is called, the CEO receives an SMS, a message is displayed on the console, and an entry is made in the log file.

Replace recursion
Two integers, A and B, are randomly generated by the program. You need to display all integers from A to B inclusive, in ascending order, if A is less than B, or in descending order otherwise. The task is implemented using recursion.

Ah, what a lovely feeling - I guess I may celebrate solving my personal task number 999... :-) The archaic word "biathlon" - one attempt, solved by 23 students so far. Just one more to complete the 1000 task challenge. Woohoo. :-) If you made it here, you should be really proud of yourself! Many people get started, but only a few actually follow through. Looks like you're one of the few. Congratulations - and good luck for all further challenges in programming and in life... ;-)

Seb, did you do any extra tasks? Cause I didn't skip a single task, yet I still haven't reached task number 900 so far.
