// the take
A personal collection of Java solutions to data-structures-and-algorithms problems, organized by topic (arrays, trees, graphs, DP, heaps, tries, etc.) with folders named after course sessions and 'doubt' clarifications. It's clearly notes from following along with a DSA course, aimed at other students studying for coding interviews rather than at developers looking for a library.
Topic coverage is genuinely broad — arrays through tries, DP, disjoint sets, and manual from-scratch implementations of stacks/queues/linked lists (array-backed, circular-array-backed, and linked-list-backed versions side by side), which is useful for seeing the tradeoffs explicitly. Problems are split into incremental folders (binarySearch1, binarySearchProblems1, binarySearchProblems2) rather than one giant file, so related exercises are at least grouped.
Every folder reuses the name 'MainClass', so nothing is importable or reusable as a library — you'd have to copy-paste individual files out to use anything. There's no README describing what's covered or in what order, and no tests, so correctness of any given solution is unverifiable without reading and running it yourself. Last pushed June 2023 with no commits since, so it's a frozen snapshot of one person's coursework, not a maintained reference. This is genuinely just useful as reading material for someone else grinding the same DSA topics, not as code you'd ever depend on.
We read the README, the directory tree and a key source file in October 2026. Nobody pays to be listed. How we judge →
