  • Data Structures in Python: Linked Lists

    Linked lists are a fundamental linear data structure where elements (nodes) are not stored contiguously in memory. Each node contains data and a reference (pointer) to the next node in the list, forming a chain-like structure. This dynamic allocation offers advantages over arrays (fixed size) when frequent insertions or deletions are necessary. Singly Linked List:…

  • Classes and Objects in Python- Object Oriented Programming & A Project
