Learn by reasoning through code

Coding practice

Build algorithmic judgment by predicting behavior, choosing data structures, tracing state, testing edge cases, and comparing solutions—not by memorizing finished code.

Current problem set

Start small, then make the reasoning transferable

Two Sum with IndicesBeginner · arrays · hash maps · complements · single-pass algorithms · time complexity

Learn the two-sum pattern by predicting state, tracing a hash map, comparing brute force, and testing edge cases in Python and TypeScript.

Subarray Sum Equals KIntermediate · arrays · prefix sums · hash maps · frequency counting · subarrays · time complexity

Learn prefix-sum counting by tracing prior cumulative totals, comparing brute force, and testing negatives and repeated prefixes in Python and TypeScript.
