# CO₂ Emissions Analysis in Africa ## Context This project was developed as part of the course **Data Structures and Algorithms** . It focuses on analyzing CO₂ emissions data across African countries using algorithmic logic, data structures, and user-driven queries. ## Objective The objective of this project is to analyze CO₂ emissions in Africa and provide flexible ways to explore the data by country, year, sector, and emission trends, while applying appropriate data structures and algorithmic reasoning. ## Dataset Overview The dataset contains CO₂ emissions data for African countries from **2000 to 2020**, including: - Total CO₂ emissions - Emissions by sector (energy, transportation, manufacturing, land-use change, etc.) - Country and year identifiers ## Project Features The program allows users to interact with the dataset through several functionalities: 1. **Search emissions by country, year, and sector** - View CO₂ emissions by sector for a selected country - Option to view data for all years or a specific year 2. **Compute total CO₂ emissions across Africa** - Calculates total emissions for all African countries - Allows querying a specific year or viewing totals across all years 3. **Identify the highest emitting country** - Determines the country with the highest CO₂ emissions for a given year - Option to view results across all years 4. **Aggregate emissions by sector** - Displays emissions for all sectors in a tabular format - Allows analysis of a specific sector across years or for a specific year 5. **Track emission trends by country** - Displays year-by-year emission trends for a selected country - Option to query a specific year 6. **Insert new emission records (simulation)** - Simulates real-time data entry by allowing user input - Automatically handles missing and numeric values - Appends the new record to the dataset 7. **Undo last insertion** - Removes the most recently added emission record - Restores the dataset to its previous state …
