Practice in context
Solve curated interview problems with starter code, examples, constraints, and a workspace built for deliberate repetition.
Algorithm learning platform
Learn DSA by seeing the hidden state.
AlgoVizuals helps you practice problems, study algorithms, and inspect visual traces so the reasoning behind each solution becomes clear, repeatable, and interview-ready.

What we do
A practice studio for algorithm intuition.
The platform combines problem solving, concept visualisation, and execution traces in one place. It is built for learners who want more than a pass/fail result: they want to see the data structure, the decision, and the next improvement.
Understand every move
Turn algorithm execution into readable traces so pointers, queues, recursion, and tables become visible instead of abstract.

Problem Bank
Problems that teach the pattern behind the answer.
Work through focused LeetCode-style challenges with examples, constraints, submissions, and visual feedback that shows why your code behaves the way it does.

Algorithms
Classic concepts, broken down into executable steps.
Study sorting, searching, graph traversal, trees, dynamic programming, stacks, queues, and linked lists with input controls and complexity notes.

Visualisations
Watch state changes instead of guessing from logs.
See arrays swap, graph frontiers expand, trees rebalance, and DP cells fill in a guided timeline with play, pause, and step controls.
