2. Rotate Left k cells Use Python Consider an array named source. Write a method/function named rotateLeft( source, k) that rotates all the elements of the source array to the left 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] rotateLeft(source,3) After calling rotateLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive.  Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations.   Remember to validate the input and display an error message if the user inputs invalid data.  Documentation and the screenshot(s) of the results.  Example:  1  2  3 4  5  6 7  8  9 the result will be :  1  4  7 2  5  8 3  6  9

//convert array of numbers from farenheit to celcius// example:// argument: [23, 32, 41, 50, 59]// return: [-5, 0, 5, 10, 15]// hint: use Array.mapfunction toCelcius(array){ } //write a function that takes an input array and returns an array of booleans (>=75) or fail (<75)// example:// argument: [20, 30, 50, 80, 90, 100]// return: [false, false, false, true, true, true]// hint: use Array.mapfunction passOrFail(array){ }

How is this program written in java?

can you please write this in java.util.scanner form and can you make it so i can copy and past it, thank you.can you please write this in java.util.scanner form and can you make it so i can copy and past it, thank you.   2D Array OperationsWrite a program that creates a two-dimensional array initialized with test data. Use anyprimitive data type that you wish. The program should have the following methods:• getTotal. This method should accept a two-dimensional array as its argument andreturn the total of all the values in the array.• getAverage. This method should accept a two-dimensional array as its argument andreturn the average of all the values in the array.• getRowTotal. This method should accept a two-dimensional array as its first argumentand an integer as its second argument. The second argument should be the subscriptof a row in the array. The method should return the total of the values in thespecified row.• getColumnTotal. This method should accept a two-dimensional array…

Exercise (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. The…

a). Write a method called createArray which takes two parameters a and b, and returns an array that has all integer from a to b.   Example 1: a = 6, b = 2 Array is [6, 5, 4, 3, 2] Example 2: a = 4, b = 8 Array is [4, 5, 6, 7, 8] Example 3: a = 4, b = 4 Array is [4]   b). In main method, you should ask the user to input two integers a and b. Then call method createArray and print out the array.         class Main {public static int[] createArray(int a, int b) {}public static void main(String[] args) {}}

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 //…
