Refactor: Improve readability, performance, and safety of the code

- Enhanced readability:
  - Used if statements with initializers (C++17)
  - Removed unnecessary else blocks via early returns
  - Grouped code logically with clearer comments

- Performance optimizations:
  - Replaced `size() == 0` with `empty()` for efficiency
  - Reduced redundant checks
  - Used `const` for immutable data

- Safety and reliability:
  - Applied `static_cast` for explicit type conversions
  - Minimized return points to improve code structure

- Modern coding style:
  - Limited variable scope more tightly
  - Applied more consistent naming
  - Removed duplicate code
