CS Learning Lab

Algorithms and cryptography as hands-on lessons: run the process, inspect each step, compare complexity, and answer short checks inside the same flow.

Study by running small systems

The first version focuses on sort visualizers and cryptography playgrounds. The structure leaves room for graphs, data structures, probability, and machine learning later.

6 sorts

Sorting Algorithms

Compare adjacent swaps, selected minimums, inserted keys, merges, partitions, and heap extraction with one shared visualizer.

VisualizerOpen
Big-O

Complexity Lab

Place O(n), O(n log n), and O(n^2) side by side so growth rate differences are visible before code timing gets noisy.

ComparisonOpen
8 topics

Cryptography

Move from Caesar and Vigenere to XOR, RSA, key exchange, and hashing with parameter controls and step cards.
