Create a method that creates a random permutation of an array of numbers such that each number has an equal chance of being placed in each position in the output array.
Step by step
Solved in 3 steps with 1 images
- 8. Repetition Use Python Language Write a method that takes in an array as a parameter and counts the repetition of each element. That is, if an element has appeared in the array more than once, then its 'repetition' is its number of occurrences. The method returns true if there are at least two elements with the same number of 'repetition'. Otherwise, return false. Input: {4,5,6,6,4,3,6,4} Output: True Explanation: Two numbers repeat in this array: 4 and 6. 4 has a repetition of 3, 6 has a repetition of 3. Since two numbers have the same repetition output is True. Input: {3,4,6,3,4,7,4,6,8,6,6} Output: False Explanation: Three numbers repeat in this array:3,4 and 6 .3 has a repetition of 2, 4 has a repetition of 3, 6 has a repetition of 4. Since no two numbers have the same repetition output is False.Method Implementation Design and implement a method to swap the first and the last element of an array. For example, 1 4 9 16 25 would be transformed into 25 4 9 16 1. Important: You don’t need to test this method in main(). You don’t need to initialize the array. You don’t print out the values in the method. All you need to do is swap the first with the last element. pubilc static void swapFirstLast(int [] arr) {Using Java programming language using the name: “Exercise2.java” that meets the following requirements: Creates an array with 100 randomly chosen integers. Prompts the user to enter the index of the array, then displays the corresponding element value. If the specified index is out of bounds, display the message Out of Bounds Hint: use the ArrayIndexOutOfBoundsException
- Create 2D array 4 *5. Ask the user to enter the number inside the array. Print the numbers organized by rows. Calculate the average for each row. Print the least average. Finally, create a method that receives a 2D array to print its elements reverse starting from the last element.Create 1 method to output the list of numbers. Output the list of numbers input by user. Output the average of all the numbers. Attach Snipping photos of source code and output. Task 2 Update above program. Create a Method that will return the largest element in the array. Attach Snipping photos of source code and output.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]
- 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 ]An array called number contains 20 integer values and must be filled with values in the following way: Fill the array with consecutive even numbers starting from 10. Start again at the first element and increase every fourth element with 3. Replace the value of the first four elements each with its square. Deduct 2 from the last 3 elements. Swap the value of element 5 and element 15. Add the value of the first element to that of the last element Add consecutive integers (starting from 1) to all even elements.Remember, the first element has a subscript of 0 and the last element (element 20) has a subscript of 19.The following must be displayed: All elements must be displayed each on a new line. Identify each element clearly. Display the highest value in the array. The lowest value in the array must be displayed. Count and display how many even values and how many odd values the array contains.Multi-Dimensional Arrays Create a multi-dimensional array of size 20 by 20. Create the following methods; • Create Board: This method will create the multi-dimensional array and initialize the values to zeros, such as this; 00000000000000000000 00000000000000000000 00000000000000000000 etc • Place Ship: This method will accept as parameters the starting coordinates of the ship, the type, and the direction. (vertical or horizontal) Then it will place the ship on the board by updating the array values to be dash characters, such as this " - " The ships: One Battleship of length 8 o One destroyer of length 2 o Two cruisers of length 4 each O • Print Board: This method will output the contents of the board. Where there are ships, the dash character will be printed, where there are no ships, the zero character will be printed. • Fire: This method will accept two coordinates from the user. If there is a ship at that location, it will update the value to X for a hit. If there is no ship, it…
