Topic: Concepts of programming Language Kindly provide a bit detailed answer 4. a) Consider the following program, written in JavaScript-like syntax:// main programvar x, y, z;function sub1() {var a, x, z;. . . }function sub2() {var a, b, y;. . .}function sub3() {var a, y, w;. . .}Given the following calling sequences and assuming that dynamic scoping isused, what variables are visible during execution of the last subprogramactivated? Include with each visible variable the name of the unit where it isdeclared.“main calls sub1; sub1 calls sub3; sub3 calls sub2.”
Ch-6 1. The first known correct software solution to the critical-section problem for n processes with a lower bound on waiting of n − 1 turns was presented by Eisenberg and McGuire. The processes share the following variables: enum pstate { idle, want_in, in_cs}; pstate flag[n]; int turn; All the elements of flag are initially idle. The initial value of turn is immaterial (between 0 andn-1).ThestructureofprocessPi isshowninthefollowingFigure.Provethatthe algorithm satisfies all three requirements for the critical-section problem.
1. Write a LINUX C code for Banker’s Algorithm to deadlock avoidance.Note: Consider a system with five processes (P0–P4) and three resources (A, B, C). There are 9 instances of resource type A, 4 instances of resource type B, and 6 instances of resource type C
Computer Science Assume we have a program with the following source code, where S1, S2, S3, S4 and S5 are systems calls we can monitor at run-time. 1) S1 2) while (S2) 3) { S3; 4) if (S4) 5) S5; 6) else S2; 7) if (...)

C has many statements for decisions and loops, while MIPS has few. Which of the following do or do not explain this imbalance? Why? 1. More decision statements make code easier to read and understand. 2. Fewer decision statements simplify the task of the underlying layer that is responsible for execution. 3. More decision statements mean fewer lines of code, which generally reduces coding time. 4. More decision statements mean fewer lines of code, which generally results in the execution of fewer operations.
Answer in python , java c++ only. Correct code and output screenshot required. Else i would downvote. In this problem, There are 109+7 metropolitan networks coordinated in a circle in this settlement and none of them are related now. Elon Tusk needs to relate a part of those metropolitan networks using only roads of a comparable size to cut down the creation cost of those roads. Because of that he gave a summary on N alludes to where a couple of alludes to can appear more than once and Q questions that you need to answer. For the inquiry you need to choose whether it is attainable to interface all of the metropolitan networks from Li to Ri on that summary using only roads of length Di. Information The chief line contains two numbers N and Q (1≤N,Q≤2⋅105 ) — the length of the assortment of metropolitan regions and the amount of requests you need to address. The ensuing lines contains N numbers addressing the assortment of alludes to. Next Q lines contain three entire numbers…
26.1-10For what number of processors do the two versions of the chessprogram run equally fast, assuming that TP = T1/P + T∞? A chess lessonTo illustrate the power of work/span analysis, this section closes with atrue story that occurred during the development of one of the firstworld-class parallel chess-playing programs [106] many years ago. Thetimings below have been simplified for exposition.The chess program was developed and tested on a 32-processorcomputer, but it was designed to run on a supercomputer with 512processors. Since the supercomputer availability was limited andexpensive, the developers ran benchmarks on the small computer andextrapolated performance to the large computer.At one point, the developers incorporated an optimization into theprogram that reduced its running time on an important benchmark onthe small machine from T32 = 65 seconds to seconds. Yet, thedevelopers used the work and span performance measures to concludethat the optimized version, which was…
Figure 4 shows a program that tries to solve the dining philosophers' problem given that itonly includes 3 philosophers who want to eat, where only 3 forks are available and eachphilosopher needs two forks. The outputs after running the program are given .In the outputs, it seems that the program never finishes executing; thus, (a) which lines of the code are considered critical section? (b) which lines of the code is (or should be) implemented as atomic operations
Please refer to this textbook: “A. Silberschatz, P. B. Galvin and G. Gagne, “Operating System Principles,”7th Edition, John Wiley & Sons Inc., 2006.” And answer the following questions: Question:The Ricart& Argwala mutual exclusion algorithm: (a) Does not depend on time stamps in messages while Lamport's does. (b) Cannot handle the case where two or more processes request the same resource at the same time. (c) Does not require a process to send messages to the entire group while Lamport's does. (d) Requires fewer messages than Lamport's algorithm.
Consider the following language assuming ∑ = {a, b} The total number of a's are even including null The a's can be either consecutive or non-consecutive The number of b's are not restricted, i.e. any number of b's Build an FA using minimum number of states. Write a regular expression. Justify your answers with examples (abbabaa, aaaa, abababab bbb are acceptd; bababbba and bbbaaa, aaa are NOT accepted).
