## Overview

This repository is a collection of independent LeetCode solutions, not a single application. The principal workflow is that an online judge supplies a problem’s inputs, invokes that submission’s function or data-structure class, and receives its result. The sampled files show standalone algorithms and no shared runtime or calls between solutions; the README is empty, so the graph groups representative problems by domain rather than implying a common execution pipeline.

Main entry points: [`1445-number-of-sub-arrays-of-size-k-and-average-greater-than-or-equal-to-threshold/number-of-sub-arrays-of-size-k-and-average-greater-than-or-equal-to-threshold.py`](https://github.com/unstoppableforce96/lc-codes/blob/main/1445-number-of-sub-arrays-of-size-k-and-average-greater-than-or-equal-to-threshold/number-of-sub-arrays-of-size-k-and-average-greater-than-or-equal-to-threshold.py) (Window average), [`643-maximum-average-subarray-i/maximum-average-subarray-i.java`](https://github.com/unstoppableforce96/lc-codes/blob/main/643-maximum-average-subarray-i/maximum-average-subarray-i.java) (Maximum average), [`239-sliding-window-maximum/sliding-window-maximum.py`](https://github.com/unstoppableforce96/lc-codes/blob/main/239-sliding-window-maximum/sliding-window-maximum.py) (Sliding maximum), [`11-container-with-most-water/container-with-most-water.py`](https://github.com/unstoppableforce96/lc-codes/blob/main/11-container-with-most-water/container-with-most-water.py) (Container water)
