Requirements

• Python 3.7+
• All dependencies are from Python standard library (no external packages required)
• See requirements.txt for details

Setup

1. Clone the repository:

git clone https://github.com/nvsahana/BuildChallenge.git
cd BuildChallenge

2. Run all tests:

chmod +x setup.sh
./setup.sh

3. Or run the interactive demo:

python3 demo.py

Assignment 1: Producer-Consumer Pattern

Implements thread synchronization with:

• Blocking queue with condition variables
• Wait/notify mechanism
• Producer and Consumer threads
• Poison pill shutdown

Run tests:

cd assignment-1
python3 main_test_producer_consumer.py

Assignment 2: Sales Analysis

Performs data analysis using:

• Lambda expressions and map()
• Stream operations
• Functional grouping with groupby()
• Aggregate functions (sum, min, max, avg)

Run tests:

cd assignment-2
python3 main_test_sales_analysis.py

Sample Output

Assignment 1: 3 tests (simple, large dataset, empty source)

Ran 3 tests in 1.278s - OK

Assignment 2: 6 tests (all aggregation methods)

Ran 6 tests in 0.001s - OK
