## Overview
#### Purpose and Scope
This is a Python exercise-solution repository, not an integrated application. It contains standalone scripts for HCLTech QA/basic programming exercises. The README documents five loop-focused tasks, while the tree also includes larger Level 1 and Level 2 solution sets.
#### Execution Model and Entry Points
Each `*.py` file is independently executable with Python 3.x from a terminal; there is no package, shared launcher, import graph, or service endpoint. Primary documented entry points are:
- `Python_Simple_Loops_Problem1_Solution.py`
- `Python_Simple_Loops_Problem2_Solution.py`
- `Python_Simple_Loops_Problem3_Solution.py`
Additional independent exercise entry points are organized as:
- `HCLTech_Level1/Solution_01.py`
- `HCLTech_Level1/Solution_35.py`
- `HCLTech_Level2/Solution_01.py`
- `HCLTech_Level2/Solution_15.py`
#### Looping Exercise Stage
The root loop scripts implement the documented basic iteration sequence: forward number output, reverse number output, ascending and descending summation, and parity-based selection/output. Their control flow is local to each script: establish a numeric range, iterate, optionally accumulate or branch on parity, then print results.
- `Python_Simple_Loops_Problem1_Solution.py`
- `Python_Simple_Loops_Problem4_Solution.py`
- `Python_Simple_Loops_Problem5_Solution.py`
#### Level 1 Solution Collection
`HCLTech_Level1` is a flat collection of 35 separately runnable Python solutions. Filename numbering, rather than a dispatcher or module API, provides the organization boundary. A consumer must choose and execute the relevant script directly.
- `HCLTech_Level1/Solution_01.py`
- `HCLTech_Level1/Solution_18.py`
- `HCLTech_Level1/Solution_35.py`
#### Level 2 Solution Collection
`HCLTech_Level2` similarly contains 15 standalone solution scripts, representing a separate difficulty/category boundary from Level 1. No evidence in the tree indicates dependencies between Level 1, Level 2, or the root loop exercises.
- `HCLTech_Level2/Solution_01.py`
- `HCLTech_Level2/Solution_08.py`
- `HCLTech_Level2/Solution_15.py`
#### Data, Control, and Integration Boundaries
Input is expected to be hard-coded exercise values or terminal interaction within individual scripts; output is console text. The repository has no persistent data store, network integration, web/UI layer, queues, build pipeline, or external runtime services. Scripts should be treated as isolated programs, so changes to one solution should not require coordinated changes elsewhere.
#### Runtime and Governance
The material runtime is CPython 3.x; the README specifically advertises Python 3.13 compatibility. There are no third-party library or infrastructure requirements. Repository documentation and licensing are rooted at:
- `README.md`
- `LICENSE`
