CONCEPT BLOGS
Multi-phase guides with mental models, worked examples, diagrams, and real edge cases — the public form of Learnisim AI's conceptual learning. Read here; train it interactively in the app.
Learn how to handle duplicate minimums in a Min Stack. Trace push(3, 5, 2, 2) to master O(1) minimum queries and track state changes correctly.
Learn the array data structure through a simple mental model of contiguous slots, worked examples of insert/delete/access, and a practical contact list application.
Understand data structures as containers with rules. Build a stack from scratch and use it to debug nested function calls—no prior experience needed.
Master space complexity by tracing memory use in a worked example. Understand the model, avoid common pitfalls, and predict real-world bottlenecks with confidence.
