- C++ Only: Karan has N items in his store (numbered 1 to N); And in i Each valid (1 <= I<= N). the weight of the i th object is Wi. As Chef is very sensitive to nature. Karan wants to arrange all the weights on one side and the weights on the other side. Karan can arrange two dependent items with the help of an exchange during a single operation. Karan needs the minimum working number required to set the All-Equal weight item on one side and the All-Odd Weights on the other. Karan cannot solve this problem so he asks you to solve it. Help Chef solve this problem. Input 1 3 187 Output 1In c++ if possible i have tried everything i can quite get it: Write a thread-safe logger implementation with interface: log(datetime timestamp, string severity, string message) that outputs lines to the console in the format: Timestamp [Severity] Message with the additional requirement that there must be a delay of at least 1 second before the line appears on the console. it must be: a. Exactly one line is printed to the console for each call to log. b. The call to log is non-blocking.Some applications require two types of accesses to the critical section-read access and write access. For these applications, it is reasonable for multiple read accesses to happen concurrently. However, a write access cannot happen concurrently with either a read access or a write access. Example: For a sequence [R1, R2, W1, R3] of requests, R1 and R2 should be able to access the critical section concurrently while W1 and R3 wait in the queue. Once R1 and R2 leave the critical section, W1 can enter the critical section while R3 waits in the queue. (a) Modify Lamport's algorithm for such applications. (b) Modify Ricart and Agrawala's algorithm for such applications.
- In early implementations of FORTRAN language, a compiler may choose to use staticallocation (i.e., allocation in the static area) for local variables and parameters, effectively arrangingfor the variables of different invocations to share the same locations, and thereby avoidingany run-time overhead for creation and destruction of stack frames. However, such an implemen-tation changes the meaning of recursive function calls.Provide a simple example and explain how its meaning changes under the “FORTRAN” semanticsas stated above, compared with standard semantics found in languages like C, Python, and Java.3. In the StackGuard approach to solving the buffer overflow problem, the compiler inserts a canary value on the memory location before the retum address in the stack. The canary value is randomly generated. When there is a return from the function call, the compiler checks if the canary value has been overwritten or not. Do you think this approach would work? Why or why not?Implement in C programming language: Question 2 Write a c program that will generate the safe sequence of process execution for the situation given below:(Use Banker’s Algorithm). Note: The code can be implemented in several different ways, but make sure the parameter remains the same as shown below. n = 6; // Number of processes m = 4; // Number of resources int alloc[6][4] = { { 0, 1, 0, 3 }, // P0 // Allocation Matrix { 2, 0, 0, 3 }, // P1 { 3, 0, 2, 0 }, // P2 { 2, 1, 1, 5 }, // P3 { 0, 0, 2, 2 }, // P4 {1, 2 , 3, 1 } }; //P5 int max[6][4] = { { 6, 4, 3, 4 }, // P0 // MAX Matrix { 3, 2, 2, 4 }, // P1 { 9, 1, 2, 6 }, // P2 { 2, 2, 2, 8 }, // P3 { 4, 3, 3, 7 }, // P4 { 6, 2 , 6, 5 } }; //P5 int avail[4] = { 2, 2, 2, 1 };…

Explain the algorithm of an assembly line scheduling problem using dynamicprogramming. You may use examples in your explanation. 2. Find an assembly line scheduling using dynamic programming source codes (Javaprogramming language) from Internet. Alterthe codes to handle random generateof input for different number of stations. 3. Add counters to count the primitive operations executed. 4. Draw a graph that shows f(n) and n, where f(n) is the total number of primitiveoperations performed, n is the number of stations. 5. Discuss the time complexity of the algorithm in term of best case, worst case andaverage caseThis is some code in C for quicksort. The quicksort works correctly, but I am trying to implement multithreading. I am trying to run the recursive calls in parallel with a limit on how much threads can be running at one time (set by the global variable 'maximumThreads'). My logic is incorrect with managing how many threads can be ran at the same time. The part that I need you to look at is after the for loop in quick sort, where I have my logic for the mutex and the conditional variable. Right now when I run my code, the program runs indefinitely. I would like help with correctly implementing this part. #include <stdlib.h>#include <string.h>#include <pthread.h>#include <stdio.h>#define SORT_THRESHOLD 40typedef struct _sortParams {char** array;int left;int right;int* currentThreads;pthread_mutex_t* mutex;pthread_cond_t* cond_var} SortParams;static int maximumThreads; /* maximum # of threads to be used *//* This is an implementation of insert sort, which…
- Abstract: the main purpose of this experiment is build real time system using PPI 8255 to control devices connected to. Problem description: assume that there are two devices are connected to port A and two sensors are connected to port B of PPI 8255. They work according to the following table Devices (DID2) 01 10 Sensors (S1S2) 00 01 10 11 11 00 Write a program to control these two devices according to the values of sensors. Each group should submit a zip file which contains the following files Code file: (assembly language code) - Simulation file Report (pdf file) (details of every single step in the code, also what have you learned from this experiment)Implement SRTF (SJF with preemption) scheduling algorithm 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 and arrival times for n number of processes.
