- import numpy as np a = np.array([1,2,3]) b = np.array([4,5,6]) You may need to use NumPy methods to answer the following questions. What is the cross product of the two vectors a and b given above? What is the dot product of the two vectors a and b given above?Q1. Produce a method that reads in a set of values (double) from the user and returns them. Use this header: public static double[] getNumsFromUser (String msg1, String msg2) The implementation of the method should start with a message to input the total number of array elements, followed by a message to enter all the array elements. The method returns the array of elements. The two strings msg1 and msg2 that are passed to the method as parameters will be the two messages that tell the user what to do. In the main class, use the following program outline to test this method: public class Q1 { public static void main(String[] args) { String s1 = "Enter number of students: "; String s2 = "Enter student grades: "; double[] numbers = getNumsFromUser(s1, s2); System.out.println(Arrays.toString(numbers)); public static double[] getNumsFromUser(String msg1, String msg2){ //your code goes here } Sample run Enter number of students: 4 Enter student grades: 12.5 23 11.5 27 [12.5, 23.0, 11.5,…Now your task is to convert array to set. Remember array to set not opposite and print that. In kotlin
- Modify the quick sort implementation in the textbook to sort the array using pivot as the median of the first, last, and middle elements of the array. Add the modified quick sort implementation to the arrayListType class provided (arrayListType.h). Ask the user to enter a list of positive integers ending with -999, sort the integers, and display the pivots for each iteration and the sorted array. Main Function #include <iostream>#include "arrayListType.h"using namespace std; int main(){ arrayListType<int> list;int num;cout << "Line 8: Enter numbers ending with -999" << endl;cin >> num; while (num != -999){list.insert(num);cin >> num;} cout << "Line 15: The list before sorting:" << endl;list.print();cout << endl; list.selectionSort();cout << "Line 19: The list after sorting:" << endl;list.print();cout << endl; return 0;} Header File (arrayList.h) Including images #include <iostream>#include <cassert>…Create a Java array FirstArray, type int, length 10. Initialize it with the multiple of 2. Print the array using comma separators. (Hint: Use Arrays.toSring method. You need to import java.util.Arrays package) Print the array with vertical line (|) separator. DO NOT put the vertical line after last element.Write a method takes two int array parameters and returns the element-wise multiplication of given two array.
- A cryptarithm is a mathematical puzzle for which the goal is to find the correspondence between letters and digits, such that the given arithmetic equation consisting of letters holds true when the letters are converted to digits. You have an array of strings crypt, the cryptarithm, and an an array containing the mapping of letters and digits, solution. The array crypt will contain three non-empty strings that follow the structure: [word1, word2, word3], which should be interpreted as the word1 + word2 = word3 cryptarithm. If crypt, when it is decoded by replacing all of the letters in the cryptarithm with digits using the mapping in solution, becomes a valid arithmetic equation containing no numbers with leading zeroes, the answer is true. If it does not become a valid arithmetic solution, the answer is false. Note that number 0 doesn't contain leading zeroes (while for example 00 or 0123 do).In the "Common Array Algorithms" section, you learned how to find the position of an element in an array. Suppose you want to find the position of the second match. You could remove the first match and start over, but that would be wasteful. Instead, adapt the algorithm from that section so that it starts the search at a given position, not zero. Complete the following code.Using JavaScriptDefine a function getMonth which accepts number from 1 to 12 as an argument and return the descriptive name of the month. For example: getMonth(1) should return January while getMonth(12) returns December, finally getMonth(-1) returns null. Use array or object to define a list of names for the month and refrain from using if statement to check the argument if it's 1, 2, etc.
- Exercise 1: Write a program that generates a sequence of 20 random values between 0 and 99 in an array, prints the sequence, sorts it, and prints the sorted sequence. Use the sort method from the standard Java library. Exercise 2: Write a program that stores a list of countries: "Egypt", "Switzerland", "Argentina", "Spain", "Portugal", "Luxemburg", etc. Initialize your array with a single statement. Then print out the array. Use the sort function as before to sort the countries in alphabetical order. Reprint your array. Exercise 3: Implement exercises 1 and 2 using ArrayList. Use the Collections.sort method for sorting. After you have printed and sorted your results, then append an additional element to each list and reprint your ArrayLists. Notice that the new items will appear just at the end and will not be sorted. Resort and print out the new ArrayLists again. To clarify, you should print out your ArrayLists after your first sort, after adding items with the…Write a Java program tat prompts user for a list of integers with 0 as the last value.Save the values in an array. Assume there can be maximum 100 values. Theprogram should have the following methods:- A method that takes the array as parameter and updates each value in thearray to the square of the value.- Another method that takes the original and modified arrays as parametersand displays the original and the squared values.D. The method construct will receive four parameters: an integer k and three arrays called old1, old2, and sumarr. The method will construct the first k elements of the sumarr array fromt the first k elements of the oldi and old2 arrays, as follows. Each element of sumarr will be equal to the sum of the corresponding elements of gldi and gld2. For example, sumarri0] will be old1[0]+old2[0], sumarr[1] will be old1[1] + old2[1] and so on. (You are using parallel arrays.) Write a complete Java program to do the following: the main program will call a series of methods to process a set of data. One method will read data into two arrays. A second method will print the values stored in an array. A third method will find the smallest of the values stored in an array. A fourth method will construct a new array from two existing arrays. A fifth method will compare the values in the two arrays. Use files for both input and output. Be sure to pass the file variable to any method that will need…
