Linked List II Summary


Linked list is a process or a way that enables us to easily edit an array  without using looping (e.g for) to count from zero to the point where we want to edit the data (also shifting is needed when editing an array).  So far, we have learned about two types of linked list. Doubly and single linked list, the first one is the circular single linked list. In circular single linked list, the last node contains a pointer to the first node which can help determine whether the data is located in the middle or in the end and also there is no storing of NULL value in the list. Secondly there is double linked list, which is a two way linked list that points to the nest data while also pointing to the previous data. Thirdly there is circular doubly linked list which is very similar to the single linked list but differ on the amount of pointer in each node (2). Just as I stated above, linked list gives us the ability to edit an array far more efficient rather than using a looping process. The reason to this is because there are processes within the linked list that enables us to do so such as Inserting and deleting certain values.

AVL Tree and B-Tree

AVL Tree and B-Tree AVL Tree ·        Introduction Before we dive into the AVL tree, we should review Binary Tree. The binary tree is one of the data structures, it features sorting, ease insertion and deletion, and searching, although being able to search at a fast rate, the binary tree has a weakness. The quickness of the methods in a binary tree depends on the height of the tree, moreover it can be as large as n-1 when it's skewed, furthermore, if this happens the searching, deletion, and insertion method’s rate will be comparable to linear search. The AVL Tree takes to resolve the weakness of the binary tree by commencing rotation’s when the tree is Imbalance. The goal of this balancing is to rotate the binary tree until it has the minimum height and. ·        Balance Factor Balance Factor is a method to adjust the balance of an AVL Tree from an imbalance state. The formula is as stated below: Balance factor = height of the left subtree – height of right sub

Stack and Infix, Prefix, Postfix Notation

Stack is one of the basic flow of data that can come from an array list or a linked list. Imagine if there was a stack of boxes or plate. The last box or plate will be the first one to be used (LiFo: Last in First out). Just like that analogy, the "Stack" concept have only one place where the data can enter and exit which is the top. We also learned about Infix, Prefix and Postfix which is the shifting of the operators in a certain expression notation and the answer to the question at the meeting was pref : / + 1 3 ^ * 100 5 30 post: 1 3 + 100 5 * 30 ^ /
