Linked List in Cpp

Linked list is a simple linear data structure formed by collection of data elements called nodes. Each node consists of a data element and link field.




There is a head node that points to the starting of the linked list.
this diagram shows a simple representation of the linked list.





Linked list can be used to implement stacks, queues, list, associative arrays, etc. 

Unlike arrays linked lists are not stored in contagious memory locations rather the are stored at any empty place in memory and the address of the next node is stored in the link field.
Also you don't need to declare the size of the linked list at the time of initialization you can dynamically keep adding elements to the linked list.

The following implementation of the linked list has the following methods implemented :

1. isEmpty() : method returns true if the list is empty

2. getHead() : returns head node

3. addToStart(): method to add a node at starting

4. addToEnd() : method to add a node at the end

5. display() : method to display all the elements of the Linked List

6. length() : method that returns the length of the Linked List

7. insert() : method to insert element at a given position in the Linked List

8. deletePosition() : method to delete a element at a given position

9. deleteData() : method to delete a data element

10. findMin() : method that returns the max element

11. findMax() : method that returns the min element

12. countOccurences() : method that returns the occurences of an element

13. pop() : pop method removes last element of the Linked List

14. tostring() : method that returns a string of all elements of the String

15. copy() :  method that returns the copy of the list

16. clear() : method that clears the Linked List

17. reverse() : method that returns reversed linked list

18. recursiveReverse() : method that recursively reverses the Linked List

19. indexOf() : method that returns index of a particular element

20. atIndex() : method that returns element at a particular position

Hashing with Quadratic Probing

Hashing is a technique used for storing , searching and removing elements in almost constant time. Hashing is done with help of a hash function that generates index for a given input, then this index can be used to search the elements, store an element, or remove that element from that index. A hash function is a function that is used to map the data elements to their position in the data structure used. For example if we use an array to store the integer elements then the hash function will generate position for each element so that searching, storing and removing operation on the array can be done in constant time that is independent of the number of elements in the array. For better look at the example below. now we face a problem if for 2 numbers same position is generated example consider elements 1 and 14 1 % 13 = 1 14 % 13 = 1 so when we get 1 we store it at the first position, but when we get 14 we see that the position 1 is already taken, this is a case of colli...
