Weighted Interval Scheduling & Dynamic Programming (Knapsack, Edit Distance) Suppose you are in the middle of a pandemic. Given a list of daily case counts to analyze, one would like to identify periods of high growth in the cases. One way to do is to look at the change in new cases from day to day. For example, suppose we have the following data: (picture) We would like to identify the period of maximal growth. In the case above, such a period would be from Days 3 through 6, which has net growth of 47 cases. Give an algorithm in pseudocode that, when given a list of daily "changes" in case rates, identifies the period of maximal growth. Give proofs of correctness and running time for your algorithm.

Only correct answer else you get downvote. The races in which three applicants took part have as of late finished. The primary applicant got a votes, the subsequent one got b casts a ballot, the third one got c votes. For every up-and-comer, take care of the accompanying issue: the number of votes ought to be added to this applicant so he wins the political decision (for example the number of decisions in favor of this competitor was completely more prominent than the number of decisions in favor of some other applicant) Kindly note that for every applicant it is important to take care of this issue freely, for example the additional decisions in favor of any applicant don't influence the computations while finding the solution for the other two competitors. Input :The primary line contains one integer t (1≤t≤104) — the number of experiments. Then, at that point, t experiments follow. Each experiment comprises of one line containing three integers a, b, and c (0≤a,b,c≤109). Output…
Q2: Consider the given scenario and answers of following questions. Scenario:University has a transport department with number of busses. Each driver notes the mileage reading of his bus daily. If a bus consumes more gasoline for less kilometers, it means that bus is less efficient. You have kilometer per litter reading of three busses in variables A, B, and C. You need to find the most efficient bus.1. First write the description in your won words, what you are going to do in this program and why?2. Secondly write the C++ code.
[In C language] The concept of a "drunkard's walk" involves an individual who starts walking aimlessly from a lamp post. With each step they take, they move randomly either north, south, east, or west, each with a 25% probability. As the individual takes more steps, they tend to forget where they started and continue taking random steps. The objective is to determine how far the individual will be from the starting point (0,0) after taking N number of steps. To simulate this random walking motion for N steps, we can create a computer program. This program should ask the user to input an integer representing the number of steps to be taken. It should work for any positive value of steps, even for a large number. However, if the user enters an invalid number (such as a negative value), the program should display an error message. After each step, the program should show the current location of the random walker with respect to the origin (lamp post). Finally, when the random…

For tax purposes an item may be depreciated over a period of several years, n.With the straight line method of depreciation, each year the item depreciates by 1/nth of itsoriginal value. With the double declining balance method of depreciation, each year the itemdepreciates by 2/nths of its value at the beginning of that year. (In the final year it is depreciatedby its value at the beginning of the year.)Write a program using **Visual Basic** that performs the following tasks:1.1 Request a depreciation of the item, the year of purchase, the cost of the item, the number ofyears to be depreciated (estimated life), and the method of depreciation. The method ofdepreciation should be chosen by clicking on one of two buttons.1.2 Display a year by year description of the depreciation.
