Please answer the following Operating Systems Question, Correctly and Completely: Suppose four cars each approach an intersection from four different directions simultaneously. Each corner of the intersection has a stop sign. Assume that traffic regulations require that when two cars approach adjacent stop signs at the same time, the car on the left must yield to the car on the right. Thus, as four cars each drive up to their individual stop signs, each waits (indefinitely) for the car on the left to proceed. Is this anomaly a communication deadlock? Is it a resource deadlock? * Please answer correctly and I will provide a Thumbs Up. Thanks.

Correct answer will be upvoted else Multiple Downvoted. Computer science.     You should stop precisely one of these boards, at any subsequent you wish. Then, at that point, the boards adjoining it get stopped one second after the fact, the boards nearby those get stopped 2 seconds after the fact, etc. At the end of the day, in the event that you stop board x, board y (for all substantial y) would be stopped precisely |x−y| seconds after the fact.    For instance, assume there are 4 boards, and the 3-rd board is stopped when the digit 9 is on it.    The board 1 stops 2 seconds after the fact, so it has the digit 1;    the board 2 stops 1 second after the fact, so it has the digit 0;    the board 4 stops 1 second after the fact, so it has the digit 0.    The subsequent 4-digit number is 1090. Note that this model isn't ideal for n=4.    When all boards have been stopped, you compose the digits showed on them from left to right, to frame a n digit number (it can comprise of driving…

On the Christmas eve, Santa Claus will start working to deliver gifts to the lovely kids. Different from previous years that he secretly delivered the gifts, this year, he indeed wants to openly deliver the gifts to the kids and wish them a merry Christmas when delivering the gifts. However, the kids each have very different sleep schedules. Kid i is awake only in a single closed time interval [ai, bi]. Santa doesn’t want to disturb the sleeping kids, so each time he will find an awake kid, give the gift to the kid, wish the kid a merry Christmas, and talk with the kid until he/she falls asleep.  However, Santa does want to meet and talk with as many kids as possible. Design a greedy algorithm which takes as input the number of kids n, and the n lists of intervals [ai, bi], and outputs the maximum number of kids m that Santa can talk to. You are expected to write the pseudocode of your algorithm.

To reduce traffic congestion in downtown Winburg, Indiana, the mayor convinces the city toset up a public transportation system. Bus-only lanes are to be established, and commuterswill be encouraged to “park and ride”; that is, to park their cars in suburban parking lots andthen take buses from there to work and back at cost of one dollar per ride. Each bus is tohave a fare machine that accepts only one dollar bills. Passengers insert a bill into the slotsas they enter the bus. Sensors inside the fare machine scan the bill, and the software in themachine uses an image recognition algorithm to decide whether the passenger has indeedinserted a valid dollar bill into the slot. It is important that the fare machine be accuratebecause, once the news gets out that any piece of paper will do the trick, fare income willplummet to effectively zero. Conversely, if the machine regularly rejects valid dollar bills,passengers will be reluctant to use the buses. In addition, the fare machine must be…

In the desert there is a jail. After rebellion the single guard has been immobilized. He watched helplessly how prisoners left one by one with different speed in different directions. Later he free himself and took a motobike with extra seat. Now he can follow footprints and pick up one prisoner at a time and bring them back to jail. Each prisoner moves with constant individual speed v_i and left the jail at time t_i. In which order the guard should bring the prisoners back in order to minimize the time?

Question 2: You are given a grid of size N x N where each cell contains a non-negative integer. You need to find the maximum sum of a path from the top-left corner to the bottom-right corner. You can only move to the right or down from each cell. Apply a dynamic programming algorithm to solve this problem and explain your approach 1. Write a text explanation of your solution in a step by step. 2. Provide a Java solution code of your proposed solution and run it on the following input int grid={(1, 3, 1}, {1, 5, 1}, {4, 2, 1}};

Suppose that a car has passed the checkpoint, A, towards the checkpoint, B, with an average speed of 150 Km/hr and reached B at 10:35:40. 1- Express the recorded time at point B in seconds. 2- If the car has reached the next checkpoint, B at 10:35:40, what will be time that this car has passed the checkpoint, A, if the distance between A and B is 100 Km? The time should be in hrs-min-sec format. Show all your calculation steps.

Given arrival and departure times of all trains that reach a railway station. Find the minimum number of platforms required for the railway station so that no train is kept waiting. Consider that all the trains arrive on the same day and leave on the same day. Arrival and departure time can never be the same for a train but we can have arrival time of one train equal to departure time of the other. At any given instance of time, same platform can not be used for both departure of a train and arrival of another train. In such cases, we need different platforms.     Example 1:   Input: n = 6  arr[] = {0900, 0940, 0950, 1100, 1500, 1800} dep[] = {0910, 1200, 1120, 1130, 1900, 2000} Output: 3 Explanation:  Minimum 3 platforms are required to  safely arrive and depart all trains.     Write the Java code for the given problem

You are tasked with shipping a number n of goods g; E {1, ... , n} to a target location t;. In your very rural area, the roads are in bad shape and often blocked by trees and the like, and also, there are only three cargo companies you can use for the transport of any good g;. You have to order one truck for each good, and know the companies' routes Pi,1, Pi2 and Pi3 they would take to all specific locations, where each route consists of a sequence of road segments that it uses. Now since you are aware of the frequent road blockages, and you want not too many of your transports to be obstructed, your aim is to pick the paths Pij for each good in such a way that max{E.EP. 1|e e E} is as small as possible. (a) Formulate the problem as an ILP, and relax to an according LP. (b) Give a rounding algorithm to compute a feasible solution starting from the LP optimum that guarantees a 3- approximation to the optimal solution, and prove its approximation guarantee.
