Python rocessin summing on different paradigms. to perfon 1. One master thread aggregating and sum the result of n slave-threads that each process sums a different range of values in a given array of 1000 random integers. Test your code on different size of data What to submit: n-locking parallel array 2. Tree-reduction: Each thread will receive an segment of array of numbers, it will fork/spawn two new slaves each perform summing on different half of the received array segment, and the parent aggregate and return the total from its two slaves to it parent thread. Start with 7 nodes thread tree, when you are comfortable, you can extend it to a full thread tree. 1. Your python code

File TesSLL.java contains a driver that allows you to experiment with these methods. Compile and run TestSLL, and play around with it to see how it works. Then add the following methods to the SinglyLinkedList class. For each, add an option to the driver to test it. Do this in incremental steps!! This means, implement and test the methods one at a time.
So how fast is the merge sort? Does it depend on the type of array? We saw with some of our previous sorts that it depended on the initial array. For example, an Insertion sort was much faster for a nearly sorted array. In this exercise, you are given the Sorter class, which contains a static mergeSort method that takes an int array and length as an input. You are also given the SortTester class which has three static methods for creating 3 different types of arrays. For this test, create one of the three arrays, then take a start time using System.currentTimeMillis(). Next, run the array through the mergeSort method in the Sorter class. Finally, record the end time and print out the results. Repeat this for the other two array types. Sample Output Random Array: ** Results Hidden ** Almost Sorted Array: ** Results Hidden ** Reverse Array: ** Results Hidden **
Hello! I need some help with my Java homework. Please use Eclipse Please add comments to the to program so I can understand what the code is doing and learn Create a new Eclipse project named so as to include your name (eg smith15 or jones15). In this project, create a new package with the same name as the project. In this package, write a solution to the exercise noted below. Implement the following method that returns the maximum element in an array: public static <E extends Comparable<E>> E max(E[] list) Write a test program that generates 10 random integers, invokes this method to find the max, and then displays the random integers sorted smallest to largest and then prints the value returned from the method. Max sure the the last sorted and returned value as the same!
please solve but not copied answer from chegg
How do you do this? JAVA

Retrieving a value using its associated key can be accomplished using anindexer, which works just like an indexer for an array. A key is passed in asthe index value, and the value associated with the key is returned, unless thekey doesn’t exist, in which a null is returned.Write short code segment demonstrates how this technique works:
Can you please help me with this, its in java. Thank you. Write classes in an inheritance hierarchy Implement a polymorphic method Create an ArrayList object Use ArrayList methods For this, please design and write a Java program to keep track of various menu items. Your program will store, display and modify salads, sandwiches and frozen yogurts. Present the user with the following menu options: Actions: 1) Add a salad2) Add a sandwich3) Add a frozen yogurt4) Display an item5) Display all items6) Add a topping to an item9) QuitIf the user does not enter one of these options, then display:Sorry, <NUMBER> is not a valid option.Where <NUMBER> is the user's input. All menu items have the following: Name (String) Price (double) Topping (StringBuilder or StringBuffer of comma separated values) In addition to everything that a menu item has, a main dish (salad or sandwich) also has: Side (String) A salad also has: Dressing (String) A sandwich also has: Bread type…
6. the grade is under 20 which is outlier, remove it from the array list. 7. Print array list using System.out.println() 8. Use indexOf to print index of 80. 9. Use get function. 10. What is the difference between get and index of? 11. Print the values of the array list using Iterator class. 12.. Delete all the values of the array list using clear function. 13. Print all the values of the array after you execute clear using System.out.println(). what is the result of using clear function? 14. What is the shortcoming of using array List?
