## Overview

This repository is a collection of independent Python data-structure demonstrations and coding-challenge solutions, not a single application. The usual workflow is to supply input to one selected exercise and receive a returned value or printed answer; the snippets do not share a runtime orchestrator. The graph highlights representative capabilities across the tree and sampled files. Links between exercises are omitted because no shared calls or data flow are evidenced.

Main entry points: [`Geeks for Geeks/Binary Search.py`](https://github.com/ghanenxra/ds-algos-deep-mind-/blob/main/Geeks%20for%20Geeks/Binary%20Search.py) (Binary search), [`SPOJ/aggressive cows.py`](https://github.com/ghanenxra/ds-algos-deep-mind-/blob/main/SPOJ/aggressive%20cows.py) (Cow placement), [`HackerEarth/Old keypad in a foreign land.py`](https://github.com/ghanenxra/ds-algos-deep-mind-/blob/main/HackerEarth/Old%20keypad%20in%20a%20foreign%20land.py) (Keypad presses), [`LeetCode/643.
