Sorting is useful as the first step in many different tasks. The most common task is to make finding things easier, but there areother uses as well. In this case, it will make it easier to determine which pair or pairs of elements have the smallest absolutedifference between them.Example[5, 2, 3, 4, 1]arr =Sorted, arr' = [1, 2, 3, 4, 5]. Several pairs have the minimum difference of 1: [(1,2), (2, 3), (3, 4), (4, 5)]. Return the array[1, 2, 2, 3, 3, 4, 4, 5].NoteAs shown in the example, pairs may overlap.Given a list of unsorted integers, arr, find the pair of elements that have the smallest absolute difference between them. Ifthere are multiple pairs, find them all.Function DescriptionComplete the closestNumbers function in the editor below.closestNumbers has the following parameter(s):int arr[n]: an array of integersReturns- int[]: an array of integers as describedInput FormatThe first line contains a single integer n, the length of arr.The second line contains n space-separated integers, arr[i].Constraints2

python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.
Java - This project will allow you to compare & contrast different 4 sorting techniques, the last of which will be up to you to select. You will implement the following: Bubble Sort (pair-wise) Bubble Sort (list-wise) [This is the selection sort] Merge Sort Your choice (candidates are the heap, quick, shell, cocktail, bucket, or radix sorts) [These will require independent research) General rules: Structures can be static or dynamic You are not allowed to use built in methods that are direct or indirect requirements for this project – You cannot use ANY built in sorting functions - I/O (System.in/out *) are ok. All compare/swap/move methods must be your own. (You can use string compares) Your program will be sorting names – you need at least 100 unique names (you can use the 50 given in project #3) – read them into the program in a random fashion (i.e. not in any kind of alpha order). *The more names you have, the easier it is to see trends in speed. All sorts will be from…
Write a program that animates the insertion-sort algorithm. Create a list that consists of 20 distinct numbers from 1 to 20 in a random order. The elements are displayed in a histogram, as shown in Figure 10.21. Clicking the Step button causes the program to perform an iteration of the outerloop in the algorithm and repaints the histogram for the new list. Color the last bar in the sorted sublist. When the algorithm is finished, display a dialog box to inform the user. Clicking the Reset button creates a new random list for a new start.
JAVA language, please add test screenshot public static int[] makeIntoPalindrome(int[] arr) Makes a palindrome from a given array by appending the smallest possible number of elements. For example, makeIntoPalindrome([1, 3, 7]) returns [1, 3, 7, 3, 1] makeIntoPalindrome([5, 4, 1, 3, 3, 1]) returns [5, 4, 1, 3, 3, 1, 4, 5] makeIntoPalindrome([1, 3, 3, 1]) returns [1, 3, 3, 1] makeIntoPalindrome([1, 4, 3, 2]) should return [1, 4, 3, 2, 3, 4, 1]. Parameters: arr - an array Returns: a new array that is a palindrome obtained by appending the fewest number of elements onto arr
Suppose an array has n elements. This _____ sorts to sort and array works as follows: Find the smallest element and place it in the first position. Then find the smallest of the remaining n-1 elements and place it in the second position. Repeat on n-2 elements, n-3 elements, ..., until the array is sorted.
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
If an array is given, identify the next bigger element for each element in the array, if one exists. If the element is not accessible, print the element itself. The next bigger element y in the array for an element x is the first element that is greater than x and appears on its right side. The element itself is the next bigger member of the array's rightmost element. Example: Given A = [ 6 8 4 3 9] the next greater element listB = [8 9 9 9 9]. use python to code
TRUE or FALSE? Suppose you have been given a sorted list of 100 names and needed to find a particular name in that list. Using binary search, it is possible that you might have to look at every location in list before finding the desired name
