Implement Priority scheduling algorithm with preemption in C programming. NOTE: Please do not print the average waiting time and the average turnaround time. You are required to compute these for each process and print the values for each process separately. Add comments in the code so that the code is understandable. Take input from the user: the number of processes, their CPU burst times, arrival times and their priority for n number of processes. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming. The output format should be as below for n number of processes: Completion time for P1: 11 Waiting time for P1: 0 Turn Around time for P1: 8 Completion time for P2: 17 Waiting time for P2: 8 Turn Around time for P2: 23 . . . .Completion time for Pn: 24 Waiting time for Pn: 42 Turn Around time for Pn: 66
Write a program in some language that has both static and stackdynamic local variables in subprograms. Create six large (at least 100 * 100) matrices in the subprogram—three static and three stack dynamic. Fill two of the static matrices and two of the stack-dynamic matrices with random numbers in the range of 1 to 100. The code in the subprogram must perform a large number of matrix multiplication operations on the static matrices and time the process. Then it must repeatthis with the stack-dynamic matrices. Compare and explain the results.
In the study of formal languages state-transition diagrams are often usedto visualize changes in a machine’s configuration as it acts on input. To visualize amachine’s configuration think of its parts: Commonly a finite set of states, a finiteinput alphabet Σ, Perhaps storage devices (a stack, input/output tapes). The states arepictured as named circles sometimes decorated with symbols to denote special states,e.g. start and final states. Changes in configuration are denoted by labeled edges andperhaps changes in storage.1. Describe how edges are labeled and their meaning for finite state machines.2. Describe how edges are labeled and their meaning for pushdown automata.3. Describe how edges are labeled and their meaning for Turing machines.

A useful operation in databases is the naturalj oin.If we view a database as a list of ordered pairs of objects, then the natural join of databases A and B is the list of all ordered triples (x,y,z) such that the pair (x,y) is in A and the pair (y,z) is in B. Describe and analyze an efficient algorithm for computing the natural join of a list A of n pairs and a list B of m pairs. Data Structures & Algorithms C-7.55

Answer the given question with a proper explanation and step-by-step solution.
In a bank, customers wait in a queue (q0) for their turn to complete a transaction. Customers who come first are served first. At a certain point when there are lots of customers waiting, a decision is taken to split the queue elements into two empty queues q1 and q2. The customers are split based on the alphabetical order of their first names. Customers with first name starting A-H are added to q1 while the others (first name starting I-Z) are added to q2. In an application, write a method named splitQueue (in an application) that accepts as parameters 3 queues, the original queue (q0) and two empty queues (q1 and q2) to be filled as described above. Write also a main method in which you read the first names of customers from the user, fill them into q0 and call the method splitQueue to split q0 elements into q1 and q2. After the split display the elements of q1 first then those of q2. The header of the method is: public static void splitQueue ( Queue q0, Queue q1, Queue q2) Note:…
2) As discussed in the class on the implementation of subprogram (call and re- turn). Which one of the statements is NOT correct? A. The Activation record format and size are dynamic B. The dynamic link points to the top of an instance of the activation record of the caller C. An activation record instance is dynamically created when a subprogram is called D. Activation record instances reside on the run-time stack
It is stated in this chapter that when nonlocal variables are accessed in adynamic-scoped language using the dynamic chain, variable names mustbe stored in the activation records with the values. If this were actuallydone, every nonlocal access would require a sequence of costly stringcomparisons on names. Design an alternative to these stringcomparisons that would be faster
