*✅ 🔤 A–Z of Data Structures* 💻⚡
*A – Array*
A collection of elements stored at contiguous memory locations and accessed using an index.
*B – Binary Tree*
A tree structure where each node has at most two children (left and right).
*C – Circular Linked List*
A linked list where the last node connects back to the first node.
*D – Deque (Double-Ended Queue)*
A structure where elements can be added or removed from both ends.
*E – Edge*
A connection between two nodes in a graph.
*F – FIFO (First In First Out)*
Principle used in queues where the first element inserted is removed first.
*G – Graph*
A set of nodes (vertices) connected by edges, used to represent networks.
*H – Heap*
A tree-based structure used in priority queues (min-heap, max-heap).
*I – Indexed Structure*
Data structure that uses indexes for faster data retrieval.
*J – Johnson’s Algorithm*
Algorithm used to find shortest paths between all pairs of nodes in a graph.
*K – k-d Tree*
A space-partitioning tree for organizing multi-dimensional data.
*L – Linked List*
A structure where elements (nodes) are connected using pointers.
*M – Matrix*
A 2D data structure storing elements in rows and columns.
*N – Node*
Basic unit of a data structure containing data and references.
*O – Ordered List*
A list where elements are arranged in a specific order.
*P – Priority Queue*
A queue where elements are processed based on priority.
*Q – Queue*
A FIFO data structure for sequential processing.
*R – Red-Black Tree*
A self-balancing binary search tree ensuring efficient operations.
*S – Stack*
A LIFO (Last In First Out) data structure.
*T – Trie*
A tree used for efficient searching of strings (prefix matching).
*U – Unrolled Linked List*
A linked list storing multiple elements per node for efficiency.
*V – Vertex*
A node in a graph structure.
*W – Weighted Graph*
A graph where edges have associated weights.
*X – XOR Linked List*
Memory-efficient linked list using XOR of addresses.
*Y – Young Tableau*
A matrix-like structure used for sorting and searching.
*Z – Zipper Data Structure*
A functional structure allowing efficient updates in trees.
