PR Title

chore: Week 2 Rust Fundamentals Assignment

Description

This pull request includes the completed implementation for Week 2: Rust Fundamentals, covering functions, control flow, loops, and enums.

Each task was developed as a separate module (task_1.rs, task_2.rs, and task_3.rs) and integrated into main.rs to demonstrate modular Rust design.

Key Features Implemented:

• Function to calculate Bitcoin value in USD.
• Loop-based mining simulation with checkpoints using while and if control structures.
• Enum and pattern matching to return RPC URLs for different Bitcoin networks.
• Modular file organization using mod and pub for clean and maintainable code structure.
