# Description

Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context. Include a proper title of the Script that is being entered.

- I updated few codes in Data Structures folder and added badges in Readme.md files as enhancement.

Script 1: [oddEvenSort.py] A python program to implement odd-even sorting or Brick Sort. It is a kind of bubble sort since it is divided into two phases, i.e. odd phase & even phase and bubble sort is implemented on each of the phases.

Script 2: [linear_search_recursion.py] Another python program to search an element linearly in an array using Recursion (Read again 💯 ) Why recursion? Because it makes the task easier and reduces time complexity.

Script 3: [circular_linked_list.py] Another python program to implement and Insert a node by taking an pointer pointing to locations one want to insert a node to. The insertion operations are carried out: 
a. in empty linked list
b. at beginning of the linked  list
c. at end of the linked list
d. in between the nodes
