Question
Imagine you want to use insertion sort for sorting a deck of cards, where the suits are ordered [Clubs, Spades, Diamonds, Hearts]. Thus, all the clubs will be ordered [Ace, 1, 2.., Queen, King], then all the Spades, etc. Create the pseudocode for this problem

- Sorting is useful as the first step in many different tasks. The most common task is to make finding things easier, but there are other uses as well. In this case, it will make it easier to determine which pair or pairs of elements have the smallest absolute difference 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]. Note As 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. If there are multiple pairs, find them all. Function Description Complete the closestNumbers function in the editor below. closestNumbers has the following parameter(s): int arr[n]: an array of integers Returns - int[]: an array of integers as described Input Format The first line contains a single integer n, the length of arr. The second line contains n…arrow_forwardIn C ++ You will need to sort whitespace-separated integers using three different sort algorithms (described here: http://theoryapp.com/selection-insertion-and-bubble-sort/ and https://en.wikipedia.org/wiki/Insertion_sort). For each of the three sorting algorithms (selection, insertion, and bubble), your program should output the initial list of numbers as well as after each swap. Note: You should use the Wikipedia entry for insertion sort. Do not perform swaps if they don't change the vector. Example Input: 1 1 6 3 8 4 2 3 9 2 4 Output: 1 Selection Sort 2 1 6 3 8 4 2 3 9 2 4 3 1 2 3 8 4 6 3 9 2 4 4 1 2 2 8 4 6 3 9 3 4 5 1 2 2 3 4 6 8 9 3 4 6 1 2 2 3 3 6 8 9 4 4 7 1 2 2 3 3 4 8 9 6 4 8 1 2 2 3 3 4 4 9 6 8 9 1 2 2 3 3 4 4 6 9 8 10 1 2 2 3 3 4 4 6 8 9 11 Insertion Sort 12 1 6 3 8 4 2 3 9 2 4 13 1 3 6 8 4 2 3 9 2 4 14 1 3 6 4 8 2 3 9 2 4 15 1 3 4 6 8 2 3 9 2 4 16 1 3 4 6 2 8 3 9 2 4 17 1 3 4 2 6 8 3 9 2 4 18 1 3 2 4 6 8 3 9 2 4 19 1 2 3 4 6 8 3…arrow_forwardQuestion in image Please explain the algorithm with the answer.

- Problem2: A square matrix can be represented by a two-dimensionalarray with N rows and N columns. You may assume a maximum size of 50 rows and 50 columns. 1. Write an algorithm MakeEmpty(n), which sets the first n rows and n columns to zero. 2. Write an algorithm Add(M1, M2, M3), which adds two matrices M1 and M2 together to produce matrix M3. 3. Write an algorithm Subtract(M1, M2, M3), which subtracts matrix M2 from matrix M1 to produce matrix M3. 4. Write an algorithm Copy(M1, M2), which copies matrix M1 into matrix M2.arrow_forwardUsing the srand() and rand() C++ library, generate a vector of integers. Prompt the user for the size of the list. The random integers should be scaled to the range 1 to 100 (see page 283). Sort the numbers using the sort function from the algorithm library and display the numbers. Then calculate the percent of numbers from 1 to 50 (including 50) and from 51 to 100. Report the percentages.arrow_forward
