Apply your HeapMax class to solve the following problem: In a research project your teammate who is responsible for data collection retrieves the rankings of a set of experiment results, and she chooses to use integers to represent the success rate of each experiment. The rankings are stored in a n*n matrix where each row and column are sorted in increasing order. Your project manager wants to know the ranking of kth most successful experiment. In other words, your task is to find the kth largest number in the matrix. Please solve the problem to help your teammate. Please note that it is the kth largest element in the sorted order, not the kth distinct element./ Example: matrix = [ [1 5, 9], [10, 11, 13], [12, 13, 15] ], k = 2, return 13. This class is named "HeapMaxApp". The method that solves this problem should be declared static and named as “kthBiggest", which accepts two required parameters:

You are given 4 items as (value, weightpairs in this format {{20, 5), (60, 20), (25, 10), (X, 25}}You can assume that the array is sorted based on the ratio. The capacity of knapsack is 50. The item no. 4 (whose weights 25) is taken fractionally to fill upto the knapsack capacity. That fraction is represented in format. What is the lowest possible value of ? weight
Implement a city database using ordered lists. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation. By using JAVA.

JAVA - How do I make this a random pull of participants instead of just a participant +1? I want the purchaser to be the same as it was input in the array, but then want the gift to be random. If that isn't possible, making both random would work as well, but either way the giver and receiver can't be the same person.The output should be something like this:a will purchase a gift for d (age: 2)b will purchase a gift for c (age: 3)c will purchase a gift for a (age: 4)d will purchase a gift for b (age: 2) import java.util.Random; public class ExchangeResults{public static void main(String[] args){UserInput userinput = new UserInput();Participant[] participants = userinput.inputParticipants(); System.out.println("Exchange Results");//PRINT MATCHESshuffleParticipants(participants);} //MAKE RANDOM MATCHESpublic static void shuffleParticipants(Participant[] participants){for (int i = 0; i < participants.length-1 ; i++){Participant p1 = participants[i];Participant p2 =…

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.
KNN is a technique used to estimate new values based on the similarity of known ones. In this assignment, your company wants you to estimate the selling price of a customer's building The price you calculate will be given to the customer as the company selling price recommendation. You decide to use Data Science techniques such as the K-Nearest Neighbor.(KNN) You will need to: Import the necessary libraries from your program. (You can use the model class sklearn.neighbors.KNeighborsClassifier, part of the package sci-kit-learn 1.1.1 (Links to an external site) or any other.

A wrestling tournament has 256 players. Each match includes 2 players. The winner each match will play another winner in the next round. The tournament is single elimination, so no one will wrestle after they lose. The 2 players that are undefeated play in the final game, and the winner of this match wins the entire tournament. How would you determine the winner? Here is one algorithm to answer this question. Compute 256/2 = 128 to get the number of pairs (matches) in the first round, which results in 128 winners to go on to the second round. Compute 128/2 = 64, which results in 64 matches in the second round and 64 winners, to go on to the third round. For the third round compute 64/2 = 32, so the third round has 64 matches, and so on. The total number of matches is 128 + 64 + 32+ .... Finish this process to find the total number of matches.

Implement a program that will populate a 6x5 matrix with randomly generated integers from 100 to 500. (1) print your matrix in a table form. (2) modify your code to multiply all odd numbers by 2 and print the matrix.

Retrieving a value using its associated key can be accomplished using anindexer, which works just like an indexer for an array. A key is passed in asthe index value, and the value associated with the key is returned, unless thekey doesn’t exist, in which a null is returned.Write short code segment demonstrates how this technique works:
Write a program that randomly fills in 0s and 1s into a 6 * 6 matrix, prints the matrix, and finds the first row and first column with the least 1s.
