Data Structures & Algorithms

Master algorithmic problem-solving through a structured curriculum—from foundational data types to advanced graph and DP strategies.

Start Learning

Back to Paths
Level 1: Fundamentals

Complexity, Arrays & Core Structs

Establish the essential mental models for evaluating code efficiency.

1. Complexity Analysis

Big-O notation, time-space tradeoffs, and asymptotic behavior.

2. Arrays & Strings

Contiguous memory, static vs dynamic sizing, and string manipulations.

3. Linked Lists

Singly, doubly-linked lists, and the fast/slow pointer paradigm.

Level 2: Intermediate Data Structures

Stacks, Trees, & Hash Maps

Master non-linear systems and fast data retrieval structures.

4. Stacks & Queues

LIFO/FIFO patterns, monotonic stacks, and sliding windows.

5. Trees & Tries

Binary logic, BSTs, depth-first traversals, and prefix trees.

6. Hashing & Maps

O(1) lookups, collision resolution, and caching mechanisms.

Level 3: Pro Algorithms

Heaps, Graphs & DP Logic

Tackle high-tier interview problems requiring robust system traversal.

7. Heaps & Priority Queues

Min/Max heaps, top K elements, and scheduling algorithms.

8. Graphs & Advanced Traversals

Network modeling, BFS level traversal, DFS paths, and Dijkstra’s.

9. Dynamic Programming & Greedy

Memoization, bottom-up tabulation, optimization, and greedy sub-problems.
