Correct answer will be upvoted else downvoted. Computer science.
There are n urban communities numbered from 1 to n, and city I has excellence computer based intelligence.
A sales rep needs to begin at city 1, visit each city precisely once, and return to city 1.
For all i≠j, a departure from city I to city j costs max(ci,aj−ai) dollars, where ci is the value floor implemented by city I. Note that there is no outright worth. Track down the base absolute expense for the sales rep to finish his excursion.
Input
The main line contains a solitary integer n (2≤n≤105) — the number of urban communities.
The I-th of the following n lines contains two integers
Output
Output a solitary integer — the base all out cost

- In a lake, the population of a particular fish species is about 1 million. Fish reproduce by 20% of the population each month, regardless of the season. In addition, fish die naturally after living for an average of 10 months. There are two separate companies (for example, A and B) fishing with 5 boats on the edge of this lake. According to current data, each boat catches 5000 fish per month. However, if the total number of boats caught in the lake increases, the number of fish to be caught by each boat decreases, as the boats will prevent each other from fishing. In addition, if the fish population in the lake increases, the fish caught per boat increases, and if the population decreases, the fish caught per boat decreases. As companies earn money from hunting, they want to buy new boats over time and enlarge their boat fleet.arrow_forwardSuppose that a manufacturing company builds n different types of robots, sayrobots 1, 2, . . . , n. These robots are made from a common set of m types of materials, saymaterials 1, 2, . . . , m. The company has only a limited supply of materials for each year,the amount of materials 1, 2, . . . , m are limited by the numbers b1, b2, . . . , bm, respectively.Building robot i requires an aij amount from material j. For example, building robot 1requires a11 from material 1, a12 from material 2, etc. Suppose the profit made by sellingrobot i is pi.

Let S = {1,2...n} be a set activities, where activity i € S has a start time si, a finish time f; and a profit p, asSociated with it. Design an dynamic programming algorithm for computing a set of compatible activities of maximum profit. Argue that the time complexity of you algorithm is O(n log(n)).

- There are three financial aid counselors. If a student’s last initial is from A – H, let them know that their counselor is Jon Stewart. If a student’s last initial is from I – Q, let them know that their counselor is Chelsea Handler. If a student’s last initial is from R – Z, let them know that their counselor is Brian Williams.Ask student for the FICO score, if it’s less than 660 tell that this student cannot have a loan.arrow_forwardThe stand rental system is going to be used by any company to search for stands, either by prices, by prices, or by types. If there is any interest then the company will request a quotation through the system. This request will be assessed by a salesman of INSIGHTS. The salesman will issue a quotation accordingly. In the case the prices are convenient, the company will reserve the stands that it is interested in. The company has three days to pay the costs of the stands. The costs are obtained from the invoice generated by the salesman. The company can cancel its reservation any time. Furthermore, before the starting of the event, an employee of INSIGHTS with the role of supervisor will generate a report about the companies that paid the fees and the current setup of the exhibition. The supervisor will also issue the necessary reminders to the companies to bring their equipment as well as bring their promotion documents to the site of the exhibition.

- Suppose you are provided an even number of people going on an adventure, and there are only two-seated rafts. All rafts are identical, weighing 20kg each. Each person is described by two parameters, their strength and weight. The speed of a raft can be calculated as the sum of strengths of both persons sitting in it, divided by the total weight of the loaded. We would like to choose the allocation of people to rafts so as to maximize the speed at which the whole group can travel, assuming that the group travels at the speed of the slowest raft in it. Develop a python code to find the maximum speed of the group which can be achieved by optimally choosing places for each person.

Once students have submitted their course requests, a computer algorithm can determine the optimal schedule for everyone. The school has concluded that it will take too long to determine the best schedule. Instead, they resort to a less sophisticated method that produces a serviceable if not ideal timetable.
