What are Data Structures?
In simple terms, data structures are ways of storing, organizing, and managing data. They provide a systematic way to store and access data so that it can be easily manipulated and used efficiently.
Why are Data Structures important?
Data structures are essential for solving complex problems efficiently. By using appropriate data structures, you can optimize the time and space complexity of your code. This means that your programs will run faster and use less memory, resulting in better performance.
Maps are similar to objects but offer more flexibility when working with keys other than strings. Unlike objects, maps preserve the order of their elements and allow any type of value as a key.
Advanced Data Structures
1. Linked Lists
Linked lists are a linear data structure where each element is connected to the next using pointers. They can be efficient for inserting and deleting elements at specific positions.
Stacks follow the Last-In-First-Out (LIFO) principle, meaning the last element inserted is the first one to be removed. They are commonly used in algorithms like depth-first search (DFS) and backtracking.
Queues adhere to the First-In-First-Out (FIFO) principle, where the first element inserted is the first one to be removed. They are often used in scenarios such as task scheduling or handling events.
