Update code so that each participant gets to purchase for another random participant. Meaning the purchaser and giver could be different people. Need output to be (potentially different giver for each person than the person purchasing them a gift):Jill purchases a gift for BobBob purchases gift for SteveSteve purchases a gift for JohnJohn purchase a gift for Jill Currently, it prints out this (which makes the exchange just between those two people instead of each person having someone different other than the person purchasing a gift for them):Jill would exchange gifts with BobSteve would exchange gifts with John 2.

re Write a program which ends when a user types a user- defined letter. 1. Get an english letter as a sentinal value(a condition of termination). 2. The user will be asked to type an english letter until a user types above sentinel value. Hint: Use char type variables for english letters. e Sample output1: Pick an english letter to terminate: t Type an english letter: y Type an english letter: w Type an english letter: p Type an english letter: h Type an english letter: t Вye. Sample output2: e Pick an english letter to terminate: g Type an english letter: h Type an english letter: g Вye.
The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which has an index, n, as parameter and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: Fibonacci(7) is 13 Note: Use a for loop and DO NOT use recursion.
The Fibonacci sequence begins with O and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13.

Q3: Interplanetary Spaceflight Milan Tusk is the richest person in the universe. After devoting decades of his life to further our space exploration technologies, he’s finally ready to retire. Being a space enthusiast, the first thing he wants to do is visit n planets p1, p2, …, pn, in this order. He’s currently on planet p0. Milan knows that the distance between planets pi and pi + 1 (for 0 ≤ i < n) is d[i]light years. His spaceship uses 1 tonne of fossil fuels per light year. He starts with a full tank and can fill up his tank at any of the n planets (but he must not run out in between two planets). There’s a huge cost to set up the spaceship for refuelling. Due to financial constraints (he’s not THAT rich), he can fill up his tank at most ktimes. In order to save money and make his spaceship lighter, Milan is looking for the smallest possible fuel tank that enables him to complete his space travel and reach planet pn. What is the smallest tank capacity that enables him to do so?…
Prompt: In python, modify the function below to plot a Gaussian distribution. Code: import matplotlib.pyplot as plt import random import numpy as np from scipy.stats import norm import seaborn as sns def clipped_hist(df, clip_threshold): newData = [x for x in df if x < clip_threshold] return newData np.random.seed(30) data = [random.gauss(0, 1) for i in range(24)] data_len1 = len(data) clip_threshold = 1.0 data = clipped_hist(data, clip_threshold) data_len2 = len(data) title = "The values clipped = " + str(data_len1 - data_len2) + " The value clipping threshold = " + str(clip_threshold) plt.hist(data) plt.title(title) plt.show()
Use java only. And aswer all tascs Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4. Compute the distance between two points using Point2D API methods. 5. A line has two special cases: horizontal line (m = 0), vertical line( m is undefined).
I'm running a 5-star restaurant and I can only have the best items on my menu. My menu offers 6 items, each represented by a number from 1-6. If an item on my menu does not sell or does not sell that much compared to others, I must act and replace it with something that sells! Identify which dishes do not sell. If every dish sells, print the set of dishes that were ordered least. Input: A single line containing the dish number that were ordered. Treat as one number. INPUT: 156356231 Output: The list of dishes not ordered in numerical order. If every dish sells, print the set of dishes that were ordered least. Separate each number with a new line. OUTPUT: 4

solve in java Integer arrays groceryItemPrices and stockRecords are read from input, containing the prices and stock records of each grocery item. Initialize variable count with 0. For each grocery item, increment count if a grocery item meets both of the following conditions: Price is greater than 20. Stock record is less than 20. Lastly, output count followed by a newline. Ex: For the input: 28 14 21 22 7 9 17 24 18 10 20 26 then the output is: 3 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class CombineArrays { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); finalintNUM_VALS=6; int[] groceryItemPrices=newint[NUM_VALS]; int[] stockRecords=newint[NUM_VALS]; inti; intcount; for (i=0; i<NUM_VALS; ++i) { groceryItemPrices[i] =scnr.nextInt(); } for (i=0; i<NUM_VALS; ++i) { stockRecords[i] =scnr.nextInt(); } /* Your code goes here */
write a program that will sort the food orders using Mergesort and to report the efficiency of the algorithm. The following are the requirements: Auto-generate the order ids randomly. You may use a random function to generate the order ids. The order id takes the form of: FD9999 (the number of digits might change according to the maximum number of orders, n, that is input by the user). -For each order id, the total cost of the order should also be auto-generated randomly. The total cost of the order will be in the following format: RM999.99. -Sort the orders using Mergesort according to the order ids.  Display the list of the unsorted orders and the corresponding total cost of the order (if this option is selected by the user)  Display the list of the sorted orders and the corresponding total cost of the order (if this option is selected by the user) - Display the running time of the sorting algorithm. You are required to: a. Implement the scenario above using C/C++ programming…
