Description

Sort algorithms have many trade-offs, in-fact even the sorted output sequences might differ.

Part 1: Your tasks for this assignment are the following:

  1. Identify at least five (5) algorithm differences that might be considered when choosing a sort algorithm.
  2. Offer examples of related sorts with the discussion of each difference considered.

Part 2: Rationalize:

You have formed a hypothesis that Big O analysis is not appropriate for comparing different sort algorithms, but rather for comparing the performance of a given sort algorithm as the number of sort keys change. (Hint: consider locality differences among sorts).

Week 3 Deliverables:

  • 5 fully documented differences among sorting algorithms.
  • Support the differences with Sort algorithms that exemplify the related characteristics.
  • Generate a summary of Sort differences.
  • Include the Big O critique.

Insert(val);}} Removal class Node { Node next; String data; public Node (String x) { data=x; next=null } } class HashTable { Node [] node; int size public HashTable (int tablesize) { size=8; DATA STRUCTURE IN JAVA node=new Node[size] } public remove (int val){ val %=node.length; Node start=Node[val]; Node end=start; if(start.data==val){ node[val]=start.next; size--; return; } while(end.next!=null&&end.next.data!=val){ end=end.next; if(end.next.next==null){ end.next=null return; } end.next=end.next.next; node[val]=start; } } 4 DATA STRUCTURE IN JAVA 5 public void main (){ HashTable hashtable=new HashTable (8) hashtable. remove(val);}} Documentation We have to create the class Node, object node to form data type that would be used in the list structure (Yazdani et al., 2016). class Node { Node next; String data; public Node (int x) { //construct data=x; next=null } } Another class HashTable has to be created. This is the class that is used to manage all the methods used in the implementation of the Hash Table (Laarman, 2014). DATA STRUCTURE IN JAVA 6 class HashTable { Node [] node; int size public HashTable (int tablesize { size=8; node=new Node[tableSize] } An array list of the type Node is created with the name node; A variable size is also set to hold the size of the Array (Qiao, 2014). Both these variables are instantiated by a constructor with takes single parameter. Method to insert an element public insert (int val) { val %=node. length Node nodeptr=new Node(Val) if(node[val]==null) { node[val]=nodeptr; } else { nodeptr. next=node[val]; node[val]=nodeptr; DATA STRUCTURE IN JAVA 7 } } This method takes one parameter “val” which is a key representative. Using mod (8, n) hashfuction the key is derived which is then tested in the hashtable to check whether it is null (Yazdani et al., 2016). val %=node. length node. length would be equivalent to 8 hence satisfies the function mod (8, n); Create an object of the type Node and give the key position. Node nodeptr=new Node(Val) After creating the object, the object position has to be tested whether the position is null. If it is empty the addition operation is performed else the addition is shifted to the next position. if(node[val]==null) { node[val]=nodeptr; } else { nodeptr. next=node[val]; node[val]=nodeptr; } } Method to remove an element public remove (int val){ DATA STRUCTURE IN JAVA val %=node.length; Node start=Node[val]; Node end=start; If(start.data==null) { Return;} if(start.data ==val){ node[val]=start.next; size--; return; } While (end.next!=null&& end.next.data!=val){ end=end. next; if(end.next.next==null){ end.next=null return; } end. next=end.next.next; node[val]=start; 8 DATA STRUCTURE IN JAVA 9 } The method takes a parameter that is used to get the key using the following function. val %=node.length; //equivalent to mode(8, n) Create an instance object at the position mapped by the key. Node start=Node[val]; Check whether the node ‘start ‘is empty. If empty then do nothing because there is no element to remove. If(start.data==null) { Return; } If the start node is not empty then proceed to test whether the node start data is equivalent to the “val” our key mapper. If (start.data ==val){ node[val]=start.next; size--; return; } If this is true the node start .data is assigned the start. next and size is decremented. Followed by a return statement to end the function. DATA STRUCTURE IN JAVA 10 If the result is false then it proceeds to the while loop and transverses through the node testing whether the next elements are null (Klein, 2016). While (end.next!=null&& end.next.data!=val){ end=end. next; if(end.next.next==null){ end.next=null return; } } When one of the above condition is successful the following statement would be executed Assigning end.next and node at the current pointer to the start. end. next=end.next.next; node[val]=start; Method Main In the main method create an istance object of the class HashTable and pass a parameter 8.

Sorting Algorithms
Introduction
Sorting technique/algorithm is an algorithm that is used to arrange items in a list in a
certain order. There are many different sorting techniques/algorithms and in this article, I will be
looking at some of the different major sorting algorithms and the key differences between these
sorting algorithms. Some of the sorting algorithms that I will be looking at include the following:
Bubble sort, Insertion sort, Heap sort, Tree sort, Selection sort, Shell sort and Quick sort.
Bubble Sort
This is a sorting technique that uses comparison as a means of sorting elements.
Usually, in this algorithm, the elements that are next to each other are compared to check if they
are in order and if they are not in order, the item i...
