Lets say have this immutable record type: public class Record { public Record(int x, int y) { Validator.ValidateX(x); Validator.ValidateY(y); X=x; Y=y; } public final int X; public final int Y; public static class Validator { public void ValidateX(int x) { if(x < 0) { throw n...

Hey there, I'm having trouble separating numbers and characters from my input string. The purpose of my program is to add,subtract,multiply and divide in postfix so i cant predict the input form as it can be anything from 2 2 3 + * (answer being 10) to 2 2 + 3 * (answer being 12). So i cant use sscanf to extract the numbers and the opera...
Hi - I'm working on a hw problem that asks me this: given a finite set of numbers, and a target number, find if the set can be used to calculate the target number using basic math operations (add, sub, mult, div) and using each number in the set exactly once (so I need to exhaust the set). This has to be done with recursion. So, for...

I can't think of an example where the reference count of a file may not be zero even when it is no longer possible to refer a directory or file. The only example that I could find for a general graph directory structure is this: (Node 1 would be the north node, Node 2 would be the node Node 1 is pointing too, and so on and so forth)...
