## Overview

This is a synced collection of interview-problem solutions, not the NeetCode platform or its GitHub Sync implementation. The README documents account connection and automatic, bulk, and per-submission sync; the source tree contains standalone algorithm submissions with no demonstrated runtime wiring between them. The graph groups representative solutions by topic. Sync links reflect README documentation, not inspected implementation; only sampled algorithms are represented.

Main entry points: [`Data Structures & Algorithms`](https://github.com/gnarendra9014-user/neetcode-submissions/tree/main/Data%20Structures%20%26%20Algorithms) (Synced repository)
