Lecture Notes Related to Liquid

Introduction to Liquid

  • This lecture was given at Sapna College.
  • The lesson in the Liquid series; the previous lesson covered the Collection Framework.
  • Three main topics of Liquid:
    • Creating a record
    • Shopping related to algorithms
    • Concept of balance

Coding and Career

  • There will be various career options in the future that we haven't imagined yet.
  • Technology will have a significant impact.
  • Practice in coding is necessary.

Linked List

  • The linked list is an important data structure.
  • It is a list of elements connected to each other.

Operations and Time Complexity

  • Insert Operation: Takes O(n) time as elements need to be shifted.
  • Search Operation: Takes O(1) time as access can be direct through the index.

Features of Linked List

  • Uses non-contiguous memory.
  • Links different data.

Internal Structure of Linked List

  • Constructs notes.
  • Each note contains data and a reference to the next.

Types:

  • Singly Linked List: Has only the next reference.
  • Doubly Linked List: Has both next and previous references.
  • Circular Linked List: The last note is connected to the first note.

Writing Code for Linked List

  • Four main operations in a linked list:
    • Add
    • Print
    • Delete
    • Size Check

Key Points in Coding

  • Construction of note class
  • Add first and add last operations
  • Delete first and delete last operations
  • Keeping track of size

Use of Collection Framework

  • Simplifying the linked list using Java collection.
  • Format of linked list: LinkedList<Type>
  • Using add, print, and remove functions.

Conclusion

  • Various operations of linked list and their usage are important.
  • Solving practice questions is essential for a better understanding of linked lists.

By using these notes, you can gain detailed information about linked lists and improve your coding skills.
