(Combine two lists) Write a method that returns the union of two array lists of integers using the following header:
public static ArrayList<Integer> union(ArrayList<Integer> list1, ArrayList<Integer> list2)
For example, the addition of two array lists {2, 3, 1, 5} and {3, 4, 6} is {2, 3, 1, 5, 3, 4, 6}. Write a test
Enter five integers for 1ist1: 3 5 45 4 3
Enter five integers for list2: 33 51 5 4 13
The combined 11st is 3 5 45 4 3 33 51 5 4 13

- 2. (Average an array) Write two overloaded methods that return the average of an array with the following headers: public static int average (int[] array) public static double average (double[] array) Write a test program that prompts the user to enter ten double values, invokes this method, and displays the average value.arrow_forwardMethod Details: public static void rotate(int[] array, boolean leftRotation, int positions) Rotates the provided array left if leftRotation is true; right otherwise. The number of positions to rotate is determined by positions. For example, rotating the array 10, 20, 7, 8 two positions to the left will update the array to 7, 8, 10, 20. Only arrays with 2 or more elements will be rotated. Hint: adding private methods that rotate an array one position to the left and one position to the right can help. Parameters: array - leftRotation - positions - Throws:java.lang.IllegalArgumentException - When a null array parameter is providedarrow_forwardShift Right k Cells (Use Python) Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftRight(source,3) After calling shiftRight(source,3), printing the array should give the output as: [ 0,0,0,10,20,30 ]arrow_forward
- please code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: (refer image1 ) Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]arrow_forward1. (Find the smallest element) Write a method that finds the smallest element in an array of double values using the following header: public static double min(double[] array) Write a test program that prompts the user to enter ten numbers, invokes this method to return the minimum value, and displays the minimum value.arrow_forwardExercise (Array and Method): Write a method called arrayToString(), which takes an int array and return a String in the form of {a1, a2, ..., an}. Take note that there is no comma after the last element. The method's signature is as follows: public static String arrayToString(int[] array) Also write a test driver to test this method (you should test on empty array, one-element array, and n-element array). Notes: This is similar to the built-in function Arrays.toString(). You could study its source code. Exercise (Array and Method): Write a boolean method called contains(), which takes an array of int and an int; and returns true if the array contains the given int. The method's signature is as follows: public static boolean contains(int[] array, int key) Also write a test driver to test this method. Exercise (Array and Method): Write a method called search(), which takes an array of int and an int; and returns the array index if the array contains the given int; or -1 otherwise.

- [In c#] Write a class with name Arrays . This class has an array which should be initialized by user.Write a method Sum that should sum even numbers in array and return sum. write a function with name numFind in this class with working logic as to find the mid number of an array. After finding this number calculate its factorial.Write function that should display sum and factorial.Don’t use divide operatorarrow_forwardvoid mystery2(int list[], int length) { for (int i = 0; i < length - 1; i++) { if (i % 2 == 0) { list[i]++; } else { list[i]--; } }} For each array below, indicate what the array's contents would be after the function were called and passed that array as its parameter. use the following as input. {6, 3} {2, 4, 6} {1, 2, 3, 4} {2, 2, 2, 2, 2} {7, 3, 2, 0, 5, 1}arrow_forward(Maximum element in an array) Implement the following method that returns the maximum element in an array . public static > E max (E[] list) Write a test program that prompts the user to enter 10 integers, invokes this method to find the max.arrow_forward
- 3. (Eliminate duplicates) Write a method that returns a new array by eliminating the duplicate values in the array using the following method header: public static int[] eliminate Duplicates (int[] list) Write a test program that reads in ten integers, invokes the method, and displays the result.arrow_forward(Average the major diagonal in a matrix) Write a method that averages all the numbers in the major diagonal in an n * n matrix of double values using the following header: public static double averageMajorDiagonal(double[][] m) Write a test program that reads a 4-by-4 matrix and displays the average of all its elements on the major diagonal.arrow_forwardWrite a method body of a method: InsertNum(int num) This method will be self intelligent to place the user entered number at desired position of the array. But at runtime it's behaviour will change in case of unsorted array it places the number in array at constant time. i.e. Big0(1) Code the method by keeping above scenario in mind.
