In Python: Design circular buffer/list based on a linked list data structure. The circular buffer should have the following properties: 1. Size of the buffer = 10 2. Insert element elements 1-10 in the circular buffer 3. Initialize the current index to 5 4. Advance the index by 8 elements and print the current index. 5. Test your code by advancing the index by 18 and 28, you should get the same index in both cases. 6. What python operation does step 5 represent?
