I have 3 threads (A, B, C) that i just can't make them work how i want them to. ALL these 3 threads share a reference to the same object - K. What i'm trying to do, is to start all 3 up, then at some point in time when thread A arrives in a certain state, pause threads B and C, until A executes some method work() and when work finishes, ...
Hello, I have, for example, such class: class Base { public: void SomeFunc() { std::cout << "la-la-la\n"; } }; I derive new one from it: class Child : public Base { void SomeFunc() { // Call somehow code from base class std::cout << "Hello from child\n"; } }; And I want to see: la-la-la Hello from child C...
An in-place algorithm with O(n) running time that rearranges an unsorted array A[0 . . . n − 1] filled with distinct integers so that, for a given k (1<=k<=n), A[0 . . . k − 1] contains the k smallest integers in increasing order. Is there an existing algorithm that meets these specifications, or one that can be altered to meet them, I ...

My professor gave my class an assignment today based on object oriented programming in Pygame. Basically he has said that the game that we are to create will be void of a main game loop. While I believe that it is possible to do this (and this question has stated that it is possible) I don't believe that this is required for adherence t...
I can't seem to get my code to create either a child class or parent class, depending on input. Here's the code: BST<countint> t; if (rst) RST<countint> t; t.print_type() // always prints "BST" RST is a child class of BST. print_type() is just a test method I wrote. RST only really inherits one method, repair(), which is virtual...
I have a search tree thats defined as data (Ord a) => Stree a = Null | Fork(Stree a) a (Stree a) deriving Show and I have to define two functions, mapStree: mapStree :: (Ord b, Ord a) => (a -> b) -> Stree a -> Stree b and foldStree: foldStree :: (Ord a) => (b -> a -> b -> b) -> b -> Stree a -> b I dont fully understand whats g...
Okay, I'm not trying to do anything super complex, I have searched, and searched, and roamed every blog and forum I can find. I am about to tear my hair out because no one just outright shows it working. I want to use an IDictionary in my Model. Nevermind the reason why, that's irrelevant. I just want to do something very simple, and u...
I have to implement a method: E[] toArray(E[] a) // Pass an array, convert to singly linked list, then return the array. from java.util Interface List<E> As I mentioned, I have to pass an array, convert it to a singly linked list, sort it, then return the array. In the Node class I have this to work with: public Node(E v, Node<...
Following set is given: X := {Horse, Dog} Y := {Cat} I define the set: M := Pow(X) u {Y} u for union The resulting set of the power set operation is: Px := {0, {Horse}, {Dog}, {Horse, Dog}} 0 for empty set My question is referenced to the unio operation. How do I unite 0 and Y? M := {{Horse, Cat}, {Dog, Cat}, {Horse, Dog, Ca...
The following is the problem I'm working on and my snippet of code. Is there a better way to implement this? I have used basic control structures for this below. Is it better to store the rows and columns in a map and searching through the map based on the key/value pairs? There is a security keypad at the entrance of a building. It...

Hi all. I've got the task of making a car rental program, which uses linked lists to control what cars are available for rent, are rented, or are in repair. The 'car' is a structure, and so is the rented list, available list, and repair list. Heres my current issue. If the user wants to make a new car available, we must add it to our l...
