## Overview

This repository is a collection of independent Python LeetCode submissions, not a single application: each solution accepts problem inputs and computes a result, with no shared runtime or cross-solution calls shown. The README organizes submissions by LeetCode topics, while the tree organizes each answer in its own problem directory. The graph groups representative solutions by algorithm domain. Because no common invocation or judge integration is evidenced in the excerpts, it does not imply connections between solutions.
