πŸ”— Linked Lists πŸ”— Linked lists are nodes connected by pointers. They're essential for dynamic data structures.

πŸ₯ž Stacks πŸ₯ž Stacks follow a Last-In-First-Out (LIFO) approach. They're like a stack of plates - you add and remove from the top.

🎫 Queues 🎫 Queues follow a First-In-First-Out (FIFO) approach. Think of them as lines at a ticket counter.

πŸ’‘ Greedy Algorithms πŸ’‘ Greedy algorithms make locally optimal choices at each step. They're your efficient problem-solving companions.

🌳 Binary Trees 🌳 Binary trees mimic hierarchical structures. Master traversal techniques to explore their branches.

πŸ” Binary Search Trees πŸ” BSTs offer efficient searching and insertion. They're the librarians of your data, organizing and retrieving information.

🏞️ Heaps/Priority Queues 🏞️ Heaps are specialized trees for maintaining priority. Think of them as organizational structures that ensure top efficiency.

πŸ—‚οΈ Hashing πŸ—‚οΈ Hashing is a magical technique for fast data retrieval. It's like indexing a library to find books quickly.

🌲 Tries 🌲 Tries are tree-like structures used for dictionary-like operations. They're your linguistic tool for word manipulation.

🌐 Graphs 🌐 Graphs connect nodes in intricate networks. They're your pathways for solving complex interconnected problems.

🧩 Dynamic Programming 🧩 Dynamic Programming (DP) is your strategy for breaking down problems into smaller subproblems and reusing solutions.

🌳 Segment Trees 🌳 Segment trees are data structures for efficient range queries. They're your search engines for intervals.
