There is an array of n integers. There are also 2 disjoint sets, A and B, each containing m integers. You like all the integers in set A and dislike all the integers in set B. Your initial happiness is 0. For each i integer in the array, if i E A, you add 1 to your happiness. If i E B, you add -1 to your happiness. Otherwise, your happiness does not change. Output your final happiness at the end. Note: Since A and B are sets, they have no repeated elements. However, the array might contain duplicate elements. Constraints 1≤ n ≤ 105 1≤m≤ 105 1 Any integer in the input < 10⁹ Input Format The first line contains integers n and m separated by a space. The second line contains n integers, the elements of the array. The third and fourth lines contain m integers, A and B, respectively.

1. Declare an array to hold eight integers. Use a for loop to add eight random integers, all in the range from 50 to 100, inclusive, to this array. Duplicates are okay. Next, pass the array to a method that sorts the array and returns another array containing only the largest and smallest elements in the original array. Print these two values in main. Then use a foreach loop to display all elements of the sorted array on one line separated by a single space. This latter loop should also count the odd and even numbers in the array and determine the sum of all elements in the array. SAMPLE OUTPUT The lowest element is 59 The highest element is 96 Here is the array 59 64 76 77 80 88 91 96 Evens: 5, odds: 3 Total: 631
The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number //…
Note: Set a random seed of 100 for this assignment. All arrays should contain random numbers between 0 and 1 (zero is inclusive). Create a one-dimensional array of twenty float random numbers. Assign the sum of these values to Q1. Assign the max of these values to Q2. Create a four by five array of random numbers. Take the minimum values in each array and create an array of those values. Assign it to Q3. Assign the mean of all the array values to Q4. Create an array with the following values: 2, 3, np.nan (this should represent a missing value), and 5. Use a numpy function to find the sum of the values in this array. Assign the sum to Q5 (you should expect a numerical value here). Create two separate arrays each containing four random numbers. Concatenate the two arrays and assign it to Q6. Create a four by four array of random numbers and call it q7. Concatenate this array with itself and assign it to Q7. Create a two by four array of…
Given an array of wine objects, write a function that returns the name of the wine he will buy for the party. If given an empty array, return null. If given an array of only one, Atticus will buy that wine. Examples chosenWine ([ { name: "Wine A", price: 8.99 }, { name: "Wine 32", price: 13.99 }, { name: "Wine 9", price: 10.99 } - "Wine 9" ])
