- Write pseudo-code for problems requiring code. Do not write Java, Python or C++. please the appropriate level of detail. For the questions asking for justification, please provide a detailed mathematically oriented discussion. A proof is not required. 1. Develop an ADT specification for a priority queue. A priority queue is like a FIFO queue except that items are ordered by some priority setting instead of time. In fact, you may think of a FIFO queue as a priority queue in which the time stamp is used to define priority.2. Write an algorithm to reverse a singly linked list, so that the last element become the first and so on. Do NOT use Deletion - rearrange the pointers. 3.What is the average number of nodes accessed in search for a particular element in an unordered list? In an ordered list? In an unordered array? In an ordered array? Note that a list could be implemented as a linked structure or within an array.4. Write a routine to interchange the mth and nth elements of a…Study the scenario and complete the question(s) that follow: The Fork/Join Framework is used for parallel programming in Java. The Fork/Join Framework when illustrated in form of a diagram resembles a fork, hence its name. A problem is divided into nonoverlapping subproblems, which can be solved independently in parallel. The solutions to all subproblems are then joined to obtain an overall solution for the problem. This is the parallel implementation of the divide-and-conquer approach. In JDK 7's Fork/Join Framework, a fork can be viewed as an independent task that runs on a thread. In this task, you are required to write a Java program in NetBeans that implements Parallel programming using the Fork/Join framework. Your program should initially generate 15 million random numbers. This should be read into an array of doubles. Then it should make use of a method that uses this array to calculate the sum of these doubles. Your program should make use of the subclasses in the Fork/Join…Examine the idea of abstraction by comparing it with various implementations found in computer science. One of the best ways to get a handle on abstraction is to examine its value in software engineering.
- Explain the difference between static and dynamic scoping, and provide concrete examples in two different programming languages. The examples should consist of short code snippets and detailed explanations.How can abstraction and encapsulation work in conjunction with one another?There are a lot of similarities between object-oriented programming and abstract data types. This is nothing more than a fluke. Are we on the same page? Offer an example or explanation to back up your position if you have one.
- Write a small library in the C programming language to do Minifloat (Links to an external site.) (8-bit binary floating-point numbers) operations. Notes You have to come up with a sensible representation and stay consistent throughout a library. The internal representation (e.g. a struct) does not have to match the external representation (e.g. just a binary pattern, or a pointer to an abstract data type). Be careful of memory leaks. For example, do not return a pointer to a local static variables in a function. Instead, allocate on the heap with malloc and then return the pointer to that. Minimum requirements Meeting these requirements will collect the regular points. add - Add two Minifloat numbers and return the result. mult - Multiply two Minifloat numbers and return the result.Explain the concept of encapsulation and decapsulation in the OSI model, illustrating with examples.What is an Abstract Data Type (ADT) and how does it work? What are the benefits of ADTs, exactly? What are some of the ways that the notion of heredity makes problem solving easier?
- Interrupts are system wide events that stops the execution of a currently running process. Examples of interrupts include (but are not limited to) mouse clicks, process termination, key presses, etc. Some interrupts are considered as more important to be handled first then the others. For example, a hardware interrupt such as hard drive read operation has lesser priority than a memory read. In this way, the most appropriate data structure for representing of such events is the priority queue. Demonstrate by writing an algorithm or a flowchart how to insert the following interrupts in a heap so the highest priority element should move out first. Interrupts Priorities INT 0 100 INT 10 51 INT 11 52 INT 21 54Given the following UML diagram, generate the corresponding “skeleton/stub” Java code for this framework.3. There are several algorithmic solutions available for solving deadlocks. If you are asked to implement one of those with Java language (compulsory), how would you do it? You are not required to write any code. But you have to present the idea from Object-oriented programming point of view.
