Answer in C++ only Ron opened his new restaurant and prepared the first free meal for everyone! You want to try a new restaurant, but because it offers free food, many people come and a huge queue has formed. Currently (at time T=OT=0) there are people waiting in the MM queue. You also know that more people are coming to NN; denote the time when the iith person stands at the back of the queue, Ai. You notice that every exactly LL seconds one seat in the restaurant becomes free and is taken by the person who is currently in the queue, i.e. at time T=LT=L one person enters, then at time T= 2L, another person enters person and the like. You don't like waiting in lines, so you want to choose the time you're standing at the back of the line so that the time between that moment and the moment you enter the restaurant is as short as possible. Suppose that if you decide to stand at the back of the queue at the same time as someone else, you will stand in front of them in the queue (closer to the restaurant). Also, you have to stand at the back of the line by KK second or you will arrive home late What is the minimum time you have to spend standing in line? Input 1

Instrument FrequencyCounter to use Stopwatch and StdDraw to make a plot where the x-axis is the number of calls on get() or put() and the y-axis is the total running time, with a point plotted of the cumulative time after each call. Run your program for Tale of Two Cities using SequentialSearchST and again using BinarySearchST and discuss the results. Note : Sharp jumps in the curve may be explained by caching, which is beyond the scope of this question.
Q2: Ginormous Campus The campus is pretty big. There are n buildings scattered around it, numbered from 0 to n-1. These buildings are so far away from each other that the only way to get from one to another is to take a campus bus. There are m campus bus routes. The i-th one (0 <= i < m) takes you from building u_i to building v_i (but not the other way around). These buses run very frequently. Professor Zingaro is deciding where to hold his CS lectures. He believes a building x is accessible from a building y if you can get from y to x taking at most two buses. For his students’ convenience, he wants to hold his lectures in the most accessible building. Help him out by telling him how many buildings the most accessible building is accessible from. In addition, list all buildings that are the most accessible. Input The first line of the input contains two space-separated integers n and m, denoting the number of buildings and bus routes, respectively. m lines follow. The i-th one…
IN JAVA Alice and Bob are playing a board game with a deck of nine cards. For each digit between 1 to 9, there is one card with that digit on it. Alice and Bob each draw two cards after shuffling the cards, and see the digits on their own cards without revealing the digits to each other. Then Alice gives her two cards to Bob. Bob sees the digits on Alice’s cards and lays all the four cards on the table in increasing order by the digits. Cards are laid facing down. Bob tells Alice the positions of her two cards. The goal of Alice is to guess the digits on Bob’s two cards. Can Alice uniquely determine these two digits and guess them correctly? Input The input has two integers p,q (1≤p<q≤9) on the first line, giving the digits on Alice’s cards. The next line has a string containing two ‘A’s and two ‘B’s, giving the positions of Alice’s and Bob’s cards on the table. It is guaranteed that Bob correctly sorts the cards and gives the correct positions of Alice’s cards. Output If Alice can…

Write a recursive method thatprints each session of dropping the cards with J's and K's. For example if you drop it 4 times in agiven session, all possible ways to drop it are as follows (in exactly the specified order): J J J JJ J J KJ J K JJ J K KJ K J JJ K J KJ K K JJ K K KK J J JK J J KK J K JK J K KK K J JK K J KK K K JK K K K
Sorting objects in the real world https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html There are 5000 people living in the town. Every day they have new COVID-19 cases. When people show symptom, they go to the hospital and put themselves in the waiting list for testing. A new person is added at the end of the list. Due to the lack of testing kit, all in the list cannot be tested. Hospital has to sort them and select a few. Since the elderly is very weak to the COVID-19, every midnight the doctors sort the people in the list by their age to decide who is taking the test for the next day depending on the availability of testing kit. Input to the program has the form where the first line indicates how many days they will do the operation. For each day, the input starts with the day number, along with the following patient list where each element represents the name of patients and the age. The input ends with the number of available testing kits. The output display, at…

Python programming: fanis chose to visit his uncle's ranch. There are s animals and n animal pens on the him. For utility reason, creature pens are built in one line. Uncle let Theofanis know that a ranch is fortunate on the off chance that you can disseminate all animals in all pens so that there are no unfilled pens and there is something like one ceaseless section of pens that has precisely k animals altogether. In addition, a ranch is great in case it's fortunate for any conveyance without void pens. Neither Theofanis nor his uncle knows whether their ranch is great or not. Would you be able to take care of them to figure it? information :The primary line contains a solitary integer t (1≤t≤105) — the quantity of experiments. The sole line of each experiment contains three integers s, n, and k (1≤s,n,k≤1018; n≤s). Output: For each experiment, print YES (case-unfeeling), if the homestead is great, or NO (case-heartless) in any case
In Python Programming language USING AVL TREE Building an automatic appointment reservation system for a very busy heart surgeon in the city. The system is going to work as follows: The patient requests for an appointment time. The system looks through the list of appointments and if there are no appointments scheduled within 10 minutes either way of the requested time, then that appointment is added to the list of appointments along with the patient ID. Otherwise, the patient is given the next available time automatically that is not within 10 minutes of any other scheduled appointment. At the appointed time, the appointment is marked as serviced and deleted from the list of appointments. You must use an AVL Tree to implement this appointment system. The reservation system should run as follows: It should run for a total of 12*25*60 minutes. At each time instant, there is a 10% probability that a new request comes in. If a new request comes in, generate a random number between the…
Need Python Solution Ramesh, Suresh, Mahesh, and Mukesh moved to a new town and searched for accommodations. Now this city is unlike any other city. This city is an apartment matrix and there are no roads. The only way to get around is through houses. If one of the friends passes the apartment once, the party will have to pay its full rent. From the apartment, you can go to the houses to the North, South, East, or West. Since Ramesh, Suresh, Mahesh, and Mukesh are best friends, they want to meet at least once a month. Also, all four are superstitious, so Ramesh goes West only, Suresh goes North only, Mahesh goes East only, and Mukesh goes South only. Any number of people can live in any apartment. The cost of all housing in the city is provided, some of which may be negligible. Negative costs mean that if a friend lives in or moves out of the apartment, the party will be paid an amount equal to the cost dispute. Now the goal of these four friends is to earn enough money to live in the…
