Hey there, I'm fairly new to Java, and I need some help figuring out a good class hierarchy and overall design for an assignment we've been given (i'm studying CS). The assignment is graph-theory related, so we were asked to create interfaces for 2 types of graphs, simple graphs and multi-graphs (which are allowed to have parallel edge...
I wrote the entire thing, but i get vague errors. I don't know what's wrong....ugh.Also, you may ask why non-recursive well my teacher has it that way for the test. void nonrec_mergesort(vector <int> & a, vector <int> & b, int s, int r) { int m = 1; while (m <= r) { int i = 0; while(s < (r-m)) { ...
How can a barrier be implemented with semaphores in Java. Will the following pseudo code work? How can it be written using java Semaphore class. N is the number of threads to be waited for at the barrier. EveryoneHasReachedBarrier is a conditional variable. Aquire(mutex) m = m + 1; if(m != N) { Release(mutex); Aquire(EveryoneH...

It's a bit silly asking homework questions here, however I'm genuinely stumped as to what this question is asking. Create a stored procedure to add results. The procedure should take four (4) parameters. These are; The student's name (first and last), the name of the apparatus and the score. When the data has been inserted,...

I was required to write a program that generate random results of 10 sport games where 10 countries are involved, and display the medal tally based on the results. I was able to generate the games' result but have no idea how to sum up the results (i.e. the number of different medals earned by each country). Below is part of my code to...
