Metadata-Version: 2.1 Name: DScollection Version: 0.0.8 Summary: A basic implementation of some data structures Author: Kishan Chauhan Author-email: kishanchauhan2006.25@gmail.com Keywords: data structures stack linked list Classifier: Development Status :: 1 - Planning Classifier: Intended Audience :: Developers Classifier: Programming Language :: Python :: 3 Classifier: Operating System :: OS Independent Description-Content-Type: text/markdown License-File: LICENCE.txt # This is very simple implementaion of Data Structure like Stack and Singly Linked List ## Main Data Structures collections:-
Stack, Singly LinkedList, Doubly LinkedList, SinglyCirclular LinkedList, DoublyCircular LinkedList. * In Stack you can use many methods. ```python 1) push(val) #provide any valu as argument to push into stack 2) pop() #It will pop or delete the top element of stack 3) peek() #It will give you the top element 4) isEmpty() #It will tell you whether the stack is empty or not 5) printStack() #It will print the stack in form of list ```

Note:- if you initialize the stack size to 5 and you push only 3 element or less then 5 element then rest of the stack will print as 0 because initially all the value in stack is 0.

--- ## In linked list I implement singly, doubly, singlyCircular. * In Singly Linked List you can use so many methods, here is the list:- ```python 1) len() 2) is_empty() #Make sure you use this method inside the print function 3) traverse() #To print the linked list 4) insertAtHead(val) #Provide any value as argument 5) insertAtTail(val) #Provide any value as argument 6) insertAtPos(val, pos) #First provide the value and then position 7) deleteHead() #It will delete the head node 8) deleteTail() #It will delete the tail node 9) deleteAtPosition(pos) #Provide the position of node you want to delete 10) insertAfter(val, newVal) #First provide the value after which you want to add a new value. E.g:- after 5 you want to add 6 then insertAfter(5, 6) 11) insertBefore(val, newVal) #First provide the value before which you want to add a new value. E.g:- before 5 you want to add 6 then insertBefore(5, 6) 12) mergeTwoLL(l1, l2) #Give two arguments. The first argument is the first linked list and second argument is second linked list 13) get_tail() #It will print the tail node 14) get_head() #It will print the head node ``` # Here is the exmaple

Stack

```python from DScollection import * #OR # from DScollection import Stack # from DScollection import SinglyLL s1 = Stack(5) #here 5 is the size of stack s1.push(1) s1.push(2) s1.push(3) s1.push(4) s1.push(5) #you can also use loop to push to avoid this number of lines s1.pop() s1.peek() s1.isEmpty() s1.printStack() ```

Singly Linked List

```python from DScollection import * #OR # from DScollection import Stack # from DScollection import SinglyLL l1 = SinglyLL() l2 = SinglyLL() l1.insertAtTail(1) l1.insertAtTail(2) l1.insertAtTail(3) l1.traverse() l2.insertAtTail(4) l2.insertAtTail(5) l2.insertAtTail(6) l2.traverse() merged_list = SinglyLL() merged_list.mergeTwoLL(l1, l2) merged_list.traverse() len(merged_list) ``` # I will update this with all the data structure with ready to use, stay updated.
