The most important changes include updating the build script, modifying test workflows, adding new functionality to utility functions, and restructuring the project directory.

Build and Workflow Improvements:

• Project0-word/build.zig: Updated the build script to include detailed comments, added steps for running and testing the application, and modified the paths of source files.
• .github/workflows/test-zig-files.yml: Updated the workflow to test files in the src directory instead of the root directory.

Project Restructuring:

• Renamed and moved several files from the root directory to the src directory for better organization:
  • Project0-word/P0-tests.zig to Project0-word/src/P0-tests.zig
  • Project0-word/count_words.zig to Project0-word/src/count_words.zig
  • Project0-word/main.zig to Project0-word/src/main.zig
  • Project0-word/utils.zig to Project0-word/src/utils.zig

Enhancements to Utility Functions:

Test Coverage:

• Project0-word/src/P0-tests.zig: Updated test cases to reflect changes in file paths and added new test cases for enhanced coverage.
• Project0-word/src/utils.zig: Added tests for new utility functions to ensure correctness.

Additional Changes:

• Project0-word/build.zig.zon: Added a new configuration file for package management and dependencies.
