MySQL database Array vs Array list vs Linked list What is Binary tree, Complete binary tree? Coding Questions: Preorder , Inorder, Postorder traversal of Binary tree (Recursively) Pattern Printing Coding question Find the length of a string without using any predefined function. Table vs Views in MySQL

Question

Accepted Answer

Understanding data structures and algorithms commonly used in MySQL databases.

Array: a data structure that stores a collection of elements in a contiguous memory location.
ArrayList: a resizable array implementation that dynamically adjusts its size as elements are added or removed.
LinkedList: a data structure where each element is connected to the next element via pointers.
Binary Tree: a tree data structure where each node has at most two children.
Complete Binary Tree: a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.
Preorder Traversal: visit the root node first, then recursively do a preorder traversal of the left subtree, followed by a preorder traversal of the right subtree.
Inorder Traversal: recursively do an inorder traversal of the left subtree, visit the root node, then do an inorder traversal of the right subtree.
Postorder Traversal: recursively do a postorder traversal of the left subtree, followed by a postorder traversal of the right subtree, then visit the root node.
Table: a collection of related data stored in rows and columns in a database.
Views: virtual tables that display a subset of data from one or more tables in a database.
