Solution: The problem of the last contest was: For the first solution you need to factor out the x and y: x*(x+1) = y*(y-1) As you can see, on both sides there is a product of 2 consecutive integers. So

Here you can keep your brain fit by solving math related problems and also earn SBI by doing so. The problems usually contain a mathematical equation that in my opinion is fun to solve or has an interesting

Solution: The problem of the last contest was: All solutions to this equation follow one general formula. This can be reached by setting the whole equation equal to a new variable z⁶: x² = y³ = z⁶ ↓ x

Solution: The problem of the last contest was: The best way to reach the 3 solutions was by thinking about how to eliminate the problem that the y in the exponents brings. One way to do this was using

The problem of the last contest was: There also was an additional condition which removed the obvious solution: x ≠ y To find the solution you could either start guessing around, or mess around with the

The problem of the last contest was: (x–n)² = -n n is the reputation of the individual participant, to make copying of the result harder. The solution is again quite simple, if you know how complex numbers

In most other contests you just have to give a random comment without thinking, but here I want to do things a bit different. In every contest I will give you some easy problem and you need to write a

The problem of the last contest was: x² = -1 The solution to this is not to hard, although it is still often teached in school that this has no solution: x² = -1 | √ ↓ x = √-1 And that's mostly it. Now

In most other contests you just have to say "GIVE ME! PLEASE!", but here I want to do things a bit different, not too much though. In every contest I will give you some easy problem and you need

Most of the computer games that feature some sort of 3d-graphics usually use 3d-projection to determine where to paint objects on your screen. You probably think projection is a hard topic, especially

Repository New Features The menu GUI now contains several buttons which can be pressed with the mouse: The buttons are triggered using the java MouseListener which I added here. The buttons simply consist

Repository New Project What is the project about? Snake3D is a game inspired by snake. The game logic is mostly the same as in snake: The snake dies if it hits itself. The snake can eat colorful tiles

Now that you know all the specialties of java it is time to do some actual programming. Java provides a pretty advanced standard library compared to other languages. That allows you to easily access useful

In java there are a few constructs that make it easier for you to create and simplify some things, but they will also make it harder for you to read other peoples code if you don't know them. a = b = c;

Java has a lot of keywords that you can add to your functions and variables. These can be useful to make the code more readable, but also to better control what is and what can be done with certain variables.
