Rotate Right k cells (use python) Consider an array named source. Write a method/function named rotateRight( source, k) that rotates 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] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
1. Shift Left k Cells Use Python Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts 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] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]

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.

Method 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 provided
1) Write a method that returns the range of an array of integers. The range is the difference between the highest and lowest values in the array. The signature of the method should be as follows. public static int computeRange(int[] values)

TASK 1 Write a Java method that returns the index of the smallest element in an array of integers. If the number of such elements is greater than 1, return the smallest index. Use the following header: public static int indexofLargestlestelement(double[] array) Write a test program that prompts the user to enter ten numbers, invokes this method to return the index of the smallest element, and displays the index.
10. Write a program to find top two maximum numbers in a array?public class TwoMaxNumbers {.
4. write a method that receives an array and shuffles the array randomly
TASK 3 Write a Java method that returns the location of the largest element in a two-dimensional array. public static int) locatelargest(double[] a) The return value is a one-dimensional array that contains two elements. These two elements indicate the row and column indices of the largest element in the two-dimensional array. Write a Java test Program that prompts the user to enter a two- dimensional array and displays the location of the largest element in the array. Here is a sample run: Enter the number of rows and columns of the array: 3 4 -Enter Enter the array: 23.5 35 2 10 Enter 4.5 3 45 3.5 |-Enter 35 44 5.5 9.6 -Enter The location of the largest element is at (1, 2)
Rewrite the client program to use the Baby class that you have done using ArrayList. You should also have the following function in this new client program: a) Enter details for each baby (name and age) and thus populate the Baby ArrayList b) Calculate and display the average age of all babies in the ArrayList c) Ask the user to enter the name of a baby, and then remove it from the ArrayList d) Allow the user to add new baby information in the ArrayList e) Output the details of each baby from the ArrayList (name and age) Compare this client program using the ArrayList with the client program you have done using array, comment on the differences between the two. Modify your client program in the last question, by adding a sort function such that when that option is selected, it sorts the ArrayList using the baby names in alphabetical order and output the details in the sorted ArrayList to a CSV (sortedbabylist.csv) file. public class Baby { private String name; private int age;…
