JAVA The following code for InsertionSort is given to us by the textbook. Trace the code stepby step using the array[55, 22, 77, 99, 66, 33, 11]on a piece of paper or using a Word document. If the code has errors, correct it and make itwork.public static void insertionSort(double[] list) {for (int i = 1; i < list.length; i++) {/** insert list[i] into a sorted sublist list[0..i-1] so thatlist[0..i] is sorted. */double currentElement = list[i];int k;for (k = i - 1; k >= 0 && list[k] > currentElement; k--) {list[k + 1] = list[k];}// Insert the current element into list[k+1]list[k + 1] = currentElement;}}
IN JAVA Exploration: Test the sorting algorithms as follows. For input sizes n = 500, n = 1,000, n = 1,500, …, n = 10,000 [That’s 20 different values of n]. For each n, create an array I of size n. Fill the array with n random integers. Create a copy M of the array I. Pass the array I to your insertion sort and record the number of comparisons. Pass the array M to your mergesort and record the number of comparisons.
For your initial post, identify a single algorithm that you use in your day to day life which involves repetition. As an example, washing each dish in a stack of dishes or a walk/don't walk sign switching from one mode to another after a set amount of time. Detail the steps of your algorithm in your post. As you detail the steps, make sure you break down each step fully. At a high level, explain how you would go about implementing the loop. Would you implement a while loop? A for loop? Would you make use of a "break statement?" Would your solution involve a nested loop?

Instead of reading in an entire list N1,N2,⋯N1,N2,⋯ all at once, some algorithms (depending on the task to be done) can read in only one element at a time and process that single element completely before inputting the next one. This can be a useful technique when the list is very big (e.g., billions of elements) and there might not be enough memory in the computer to store it in its entirety. Write an algorithm that reads in a sequence of values v≥0, one at a time, and computes the average of all the numbers. You should stop the computation when you input a value of V = −1. Do not include this negative value in your computations; it is not a piece of data but only a marker to identify the end of the list. Write a java program and please share the code / an example of the code working.
1. a.An algorithm can be specified in various ways. Identify and explain four ways in which an algorithm can be specified. b. (b). Two algorithms A, B sort the same problem. When you go through each algorithm and break them down into their primitive operations, each can be represented as follows:A = 2n7 + 100n4 + 26n + 50 B = 7n4 + 22n2 + nlogn + 200For very large values of n, which of the algorithms A or B will runin the shortest time to solve the problem and why? (c). Two Computer Science students, Priscilla and Julius, are discussing how to compare two algorithms for solving a given problem. Priscilla suggests that they should use the execution times of the algorithms as criterion; but Julius insists that they should use the number of statements the algorithms execute as criterion. (i). Discuss the reasons why both criteria they are considering are not good for comparing algorithms.(ii). Recommend an ideal solution/criterion that they should rather use for comparing algorithms
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. You are given a string s of even length n. String s is twofold, at the end of the day, comprises just of 0's and 1's. String s has precisely n2 zeroes and n2 ones (n is even). In one activity you can invert any substring of s. A substring of a string is an adjoining aftereffect of that string. What is the base number of tasks you really want to make string s rotating? A string is rotating if si≠si+1 for all I. There are two kinds of exchanging strings overall: 01010101... or on the other hand 10101010... Input The principal line contains a solitary integer t (1≤t≤1000) — the number of experiments. The principal line of each experiment contains a solitary integer n (2≤n≤105; n is even) — the length of string s. The second line of each experiment contains a parallel string s of length n (si∈ {0, 1}). String s has precisely n2 zeroes and n2 ones. It's surefire that…
Write a simple code (python). Given a list of n elments with each element between 1 and n. determine whether there are any duplicates. Then find the following: 1. What does the algorithms compute? 2. What is its basic operation? 3. How many times is the basic operation executed? 4. What is the efficiency class of the algorithm? Keep in mind it's an Analysis of Algorithms course.

Create an Eclipse Java project to practice "Bubble Sort" algorithm presented below. Project should print unsorted and sorted sample array of 30 random integers from 0 and 1000 inclusive, your own bubble sort method implementation should be called in the main() method of your project to sort the array. Bubble Sort Algorithm: To sort an array A[0..N-1]:for (int last = N -1; last >= 1; last --){// Move the largest entry in A[0...last] to A[last]for (int index = 0; index <= last-1; index++){ //swap adjacent elements if necessaryif (A[index] > A[index+1]){int temp = A[index]; A[index] = A[index+1];A[index + 1] = temp;}}}
