In this programming assignment, you are expected to design an experimental study for thecomparison between Hoare’s partitioning and Lomuto’s partitioning in Quicksort algorithm.You must implement the recursive Quicksort algorithm using two partitioning algorithms inJava. You must design the experiments for the comparison of two algorithms both theoreticallyand empirically. You must write a detailed report including the pseudo-code of the algorithms,the time complexity of the algorithms, the experimental design, and your results. You canprovide some plots (scatter, line etc.) to illustrate your results.
Q: You are required to code two processes; the first shall simulate the first process and other the arrival of second process. These processes can come at any time, in any order. The first process shall call a procedure called FirstHere on the arrival of first process. Similarly, the second process shall call a procedure called SecondHere on the arrival of second process. The two processes will simulate the arrival of processes at random intervals and should run for a while to show around 10 queues leaving with different safe combinations. Before terminating you must clean up the semaphores and shared memory segments from the system. You must output the progress of the processes. Use semaphores to implement the solution. Note: Code in C++ and it must not be copied from somewhere else or else 11l downvote your answer.

For problems #2, create a single console application. In it (and outside the curly brackets of "class program"), create a class "MyLab06". All the following functions must be defined in this new class with public scope. Also illustrate calling each function from void main in the class "program". 2. Develop a public function that calculates and returns the average length of a server queue. For an while for an M/G/1 queue M/M/1 queue (single server, exponential processing and arrival rates), L, = 1-p ao+p. ; p is utilization of 2(1-р)" (single server, exponential arrival rate and any distribution for processing rate) Lg = the server (a value > 0 and 0), and o, is the standard deviation of the server processing time (value > 0). These values should be passed to the function (A and Os should be optional arguments). Use an enumeration to define the queue type. The function should print an error message and then throw an exception if any of the arguments are out of range.
Use a heap to implement a simulator for a process scheduling system. In this system, jobs will be read from a file consisting of the job id (a six-character string), the length of the job (an int representing seconds), and the priority of the job (an int where the higher the number the higher the priority). Each job will also be assigned an arrival number (an int representing the order of its arrival). The simulation should output the job id, the priority, the length of the job, and the completion time (relative to a simulation start time of 0).
Problem: A A class octopus has a dummy head which has four pointers – left, right, top and bottom. You have to build link list in these 4 directions depending on the input commands. There will be four types of commands - L, R, T and B. Their specifications are given below: Lx: insert x in the left link list Rx: insert x in the right link list T x: insert x in the top link list // Where x is an integer number. Bx: insert x in the bottom link list Input: Test case will start with a number n indicating the number of lines following it. Output: you have to give output that which link list (Left, Right, Top and Bottom) has maximum sum of values. See the sampl and output.

It is possible to demonstrate the return address of a function by using a series of instructions. Keep in mind that any modifications to the stack must not prohibit the process from returning control to the person who called it.
Write a Perl program that uses a hash and a large number of operationson the hash. For example, the hash could store people’s names and theirages. A random-number generator could be used to create threecharacter names and ages, which could be added to the hash. When aduplicate name was generated, it would cause an access to the hash butnot add a new element. Rewrite the same program without using hashes.Compare the execution efficiency of the two. Compare the ease ofprogramming and readability of the two.
To better understand the concept of recursion, let’s look at an example that’s quite familiar to computerusers—the recursive definition of a file-system directory on a computer. A computer normally stores related filesin a directory (also called a folder). A directory can be empty, can contain files and/or can contain other directories,usually referred to as subdirectories. Each of these subdirectories, in turn, may also contain both files anddirectories. If we want to list each file in a directory (including all the files in the directory’s subdirectories), weneed to create a function that first lists the initial directory’s files, then makes recursive calls to list the files in eachof that directory’s subdirectories. The base case occurs when a directory is reached that does not contain anysubdirectories. At this point, all the files in the original directory have been listed, and no further recursion isnecessary. Write a print_directory function that recursively walks through the…

1. Given a global list of users and password like the following, write a function (called login) that takes a user name and password and logs in the user if login is successful:- the user exists in the list- and the password is correct The function should return a True/False users = {'Jane': 'Password123@', 'John': 'Password123!'} 2. Write a function called register that takes a user name and password and adds the user to the list if the user does not already exist in the listThe function should return a True/False Put it all together: 3. Write a showmenu function that shows the following options and reads the choice from user and returns it: 1: register 2: login 0: logout 3. In the main section, based on the user's selected option, ask the required input (user name, passwords) and perform the requested operation. 4. Repeat the above until the user enters 0. (keep showing the menu that asks for another option)
