- Researchers are trying to use machine learning algorithms to make redistricting more equitable and efficient. For a sample of six zones (labelled Z1-Z6), each zone can be described by at least one letter (A-F), which is a qualitative measure of that zone. One part of the algorithm is to output a potential district layout, which can only happen if each zone can be matched to exactly one letter.Consider the following descriptions for one sample of six zones: Z1 matches B or D; Z2 matches C, E, or F; Z3 matches A or F; Z4 matches B or D; Z5 matches C or F; and Z6 matches D.(a) Draw the bipartite graph that models the zones (Z1-Z6) and the letters they match (A-F).(b) Use Hall’s theorem to determine if algorithm will be able to successfully create a district layout.The classic example of following a greedy algorithm is making change. Let’s say you buy some items at the store and the change from your purchase is 63 cents. How does the clerk determine the change to give you? If the clerkfollows a greedy algorithm, he or she gives you two quarters, a dime, and three pennies. That is the smallest number of coins that will equal 63 cents (given that we don’t allow fifty-cent pieces). It has been proven that an optimal solution for coin changing can always be found using the current American denominations of coins. However, if we introduce some other denomination to the mix, the greedy algorithm doesn’t produce an optimal solution.Write a program that uses a greedy algorithm to make change (this code assumes change of less than one dollar).The classic example of following a greedy algorithm is making change.

- Let's consider a long, quiet country road with houses scattered very sparsely along it. (Picture the road as a long line segment with an eastern endpoint and a western endpoint.) Further let’s suppose that despite the bucolic setting, the residents of all these houses are avid cell phone users. You want to place cell phone base stations at certain points along the road, so that every house is within four miles of one of the base stations. Give an efficient algorithm that achieves this goal using as few base stations as possible. Prove its correctness and explain its time complexity.There are n students who studied at a late-night study for final exam. The time has come to order pizzas. Each student has his own list of required toppings (e.g. mushroom, pepperoni, onions, garlic, sausage, etc). Everyone wants to eat at least half a pizza, and the topping of that pizza must be in his reqired list. A pizza may have only one topping. How to compute the minimum number of pizzas to order to make everyone happy?You are given the midsem and endsem marks for the N Students in the course. A student P is said to dominate a student Q, if the midsem and endsem marks of P are both greater than the respective midsem and endsem marks of Q. Design an efficient algorithm for finding all the students that are not dominated by any other student in the class.
- X-Kingdom has trapped n number of soldiers of their opponent. They want to execute them. They created a strategy so that the prisoners will kill each other and at the end one prisoner will be alive and eventually released. As part of the process, they assigned each trapped soldier a sequence number starting from 1 and ending at n. If n = 5 and k = 2, then the safe position is 3. Firstly, the person at position 2 is killed, then person at position 4 is killed, then person at position 1 is killed. Finally, the person at position 5 is killed. So, the person at position 3 survives. If n = 7 and k = 3, then the safe position is 4. The people at positions 3, 6, 2, 7, 5, 1 are killed in order, and the person at position 4 survives. Input:n and k Output:Print the list of prisoners in reverse order from n to 1Then reverse the list to print it in correct order from 1 to nDisplay the position number who will survive. You must have to use circular doubly linked list for your solution.X-Kingdom has trapped n number of soldiers of their opponent. They want to execute them.

You're considering n friends, but you know that they will have a good time only if each of them knows at least k others at the party. (Assume that if A knows B, then B automatically knows A.)

- A salesman would like to visit a set of n cities. The cities are connected pairwise by a direct trains. The cost of a train ticket varies depending on the cities it connects. This salesman would like to fly into one city, then use trains to visit each city exactly one, and then fly out of the last city on his trip. The cost of his trip is the total cost of all the train tickets (the plane tickets are not included). The salesman may chose any city to fly into and any city to fly out of. Let the problem of determining if there is a trip that costs at most k dollars be called T rainSalesman.
