Data structures are essential for organizing and managing data efficiently. Here's a quick overview of core concepts:
Arrays
- 📌 Fixed Size: Arrays have a predetermined size, making them ideal for scenarios with known data volume.
- 🚀 Fast Access: Elements are accessed via indexes (e.g.,
array[0]
), enabling O(1) time complexity for retrieval.
Linked Lists
- 🧠 Dynamic Growth: Nodes are linked, allowing flexible resizing during runtime.
- 🔁 Efficient Insertions: Adding/removing elements in the middle is efficient (O(1) with pointers).
Stacks & Queues
- 📦 LIFO Principle: Stacks follow Last-In-First-Out (e.g., browser history).
- 🚫 FIFO Principle: Queues follow First-In-First-Out (e.g., print job scheduling).
Trees & Graphs
- 🌳 Hierarchical Structure: Trees store data in parent-child relationships (e.g., file systems).
- 🌐 Networked Relationships: Graphs represent connections between nodes (e.g., social networks).
