summing on different paradigms. 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. 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 its parent thread. Start with 7 nodes thread tree, when you are comfortable, you can extend it to a full thread tree. Test your code on different size of data What to submit: 1. Your python code

Homework 7: Merging two sorted arrays Due date: Saturday March 18. Objectives: Learn to implement algorithms that work with multiple arrays. Understand the Merging algorithm. IMPORTANT. Carefully study Lecture 1 from Week 8 on D2L before you start on this. Sometimes we need to combine the values in two sorted sequences to produce a larger sorted sequence. This process is called Merging. As an example, if the first sequence (S1)contains the numbers 2 3 4 4 5 9 and the second sequence (S2) contains the numbers 1 4 5 8 9 11 12 13 17 the output sequence will contain 1 2 3 4 4 4 5 5 8 9 9 11 12 13 17 Each sequence can be stored in an array. The strategy is as follows: Start by comparing the first items in the two input arrays. Write the smaller number to the output array, and move to the the next item in that array. This is repeated until we reach the end of any one of the input arrays; thereafter, we simply copy all the numbers from the other input array to the output array. (In the…

Create your own called class called Stack Your class should store items transparently. You should add items using a Push method and remove them through the Pop method. Add an IsEmpty method should return whether there are any items in the stack or not. A CountItems method should tell you the current number of items in the stack Write some code to test your Stack class using the shapes in part 1.

Mergesort is a method that takes an integer array and returns a sorted copy of the same array. It first sorts the left half of the input array, then the right half of the input array, and finally merges the two sorted halves together into a sorted version of the input array. Implement the mergesort method public static int[] mergesort(int[] arr) { return new int[] {-1}; } *must be in this layout and done in java
Lab 16 Implementing bubble sort In this lab, you will implement the bubble sort algorithm. The bubble sort is so called because it compares adjacent items, "bubbling" the smaller one up toward the beginning of the array. By comparing all pairs of adjacent items starting at the end of the array, the smallest item is guaranteed to reach the beginning of the array at the end of the first pass.The second pass begins again at the end of the array, ultimately placing the second smallest item in the second position. During the second pass, there is no need to compare the first and second items, because the smallest element is guaranteed to be in the first position.Bubble sort takes at most n - 1 passes for an array of n items. During the first pass, n - 1 pairs need to be compared. During the second pass, n - 2 pairs need to be compared. During the ith pass, n - i pairs need to be compared. During the last pass, n - (n - 1) or one pair needs to be compared. If, during any pass, no two…
