For no reason other than to play with Java streams, I am wondering how I could simplify the following code any further. It was using an iterator previously and figured I would migrate it to using Java streams. Am I doing this right? I am sure there are a vast number of ways to rewrite this code b...

I wrote a simple function that converts an array of words into proper case (using bit shifting) and returns the array. I performed a simple test using std::chrono to check how fast it was able to perform the conversion. Using a vector of 1000 words the function was able to do it in an average of ...

I would like to write a C++ code for the n-queens problem using the permutation approach. This means I index the queens from 1 to n, and the state of the checkerboard will be defined by an array where the i-th entry stores the row of the queen at the i-th column. Clearly, such array will contain ...

I started to learn JavaFX a few days ago and I have just created as an exercise a simple Gem Puzzle game. The puzzle pieces can be moved if we click on them. The visual aspect of the game is very basic. The code is based on a MVC architecture. It's not totally finished. Still, before I get any f...

I haven't written a linked list from scratch in a couple years, so I decided to take a stab at it again. After working on it on and off for a little over a week, I'm finally happy with it. It implements Sequence. Since it overrides each method, having it extend an ABC wasn't really necessary, bu...

I'm a newbie playing around with Fortran 90 and openmp and wrote the code below (a simple 2D heat transfer simulation) for testing purposes. So far I don't see any speedup by using openmp / parallel processing. In fact, it gets slower when I use more procs. I understand that the parallelization ...
